Bug description

I am running a docker swarm with 7 nodes 3 managers and 4 workers. I have deployed portainer via the stack file, with agents and portainer it's self. After some time an agent instance will report high cpu usage 60-70% and the portainer instance will not load any data about services, stacks etc.

When i look at the log files for the agent with the high CPU i get:

2018/06/22 13:48:35 [ERR] memberlist: Error accepting TCP connection: accept tcp [::]:7946: accept4: too many open files

Expected behavior
I would expect that the portainer instance loads all the data it can, so i can continue to use it as much as possible. An error message explaining that it was unable to contact an agent would also be helpful.

Steps to reproduce the issue:
I do not have any specific steps to reproduce it. Just seems to happen randomly.

Technical details:

  • Portainer version: 1.18.0
  • Docker version (managed by Portainer): 18.03.1-ce
  • Platform (windows/linux): Amazon Linux AMI release 2018.03
  • Command used to start Portainer (docker run -p 9000:9000 portainer/portainer): sudo curl -L https://portainer.io/download/portainer-agent-stack.yml -o portainer-agent-stack.yml
    sudo docker stack deploy --compose-file=portainer-agent-stack.yml portainer
  • Browser: Firefox 60.0.2 (64-bit)

We have experienced this issue again with nearly 1000000 log messages in 3 mins. Any update on this?

Sorry @Umaaz we were not able to investigate this yet, I've referenced a network instability issue with serf inside AWS, might be related: hashicorp/serf#512

I know that @mrmachine is another AWS user, have you seen the same issues?

I am running portainer as a service on a dedicated server. The same error occurs for me. A restart helps, but after some time (within 24 hours) the error re-occurs. So this is not only occurring on AWS.

@daneZz are you using the agent setup?

@deviantony I used the "Deploy Portainer without Docker" part from the documentation on https://portainer.readthedocs.io/en/latest/deployment.html.

I figured why this happens. It seems that the connection amount of portainer continuously increases. I suspect that connections are properly closed.

Environment
Portainer version: 1.19.1 (runs as a service in Linux, not in a docker container).

I am running a docker swarm with 10 docker servers. (DESTINATION_*). The portainer service is running on a dedicated server.

Any Updates on this? I ran into the same issue again running portainer simply with:

docker run -d -p 9000:9000 -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer

On an AWSLinux2 Host connected to 4 Docker Endpoints. It wasn't even running for 24 Hours before i had to restart portainer.

Portainer Version: 1.19.1
Docker Version: Docker version 18.03.1-ce, build 3dfb8343b139d6342acfd9975d7f1068b5b1c3d3

I'm curious if this could be caused by the recently introduced snapshot feature. Can anyone try to reproduce this error with the snapshot feature disabled ? Use the --no-snapshot flag to disable it.

E.g. docker run -d -p 9000:9000 --name portainer --restart always -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer --no-snaspshot

Have never heard of a snapshot feature - and if I search in the documentation (https://portainer.readthedocs.io/en/stable/search.html?q=snapshot&check_keywords=yes&area=default) for "snapshot" nothing pops up. So I have no clue if adding the flag will help.

@guppie70 snapshots were introduced in 1.19.1, it will periodically poll the endpoints you have defined in Portainer to refresh the information available in the home view.

Flags are missing from the configuration section of the docs, will update it.

I'm thinking that this might be related to the snapshot feature but I'm not sure so it would be keen of you to try with this flag.

@guppie70

@deviantony I have re-initiated my portainer container with the --no-snapshot flag. Since I do not know how to enforce the error, we will need to wait and see if portainer keeps running in the coming period. I am happy to share any other information that might help you to locate the problem though. Just let me know!

Got the same issue on our setup:

  • Docker Swarm
  • Portainer 1.19.1
  • Running Portainer Agent Stack Deployment

It takes 2 - 3 days till these errors come up. I only need to restart portainer UI. Agents can keep on running.

We see three error types:

First, Portainer UI gets 4 - 8 of the following errors, 5 minutes in between these errors:
cron error: endpoint snapshot error (endpoint=someHost, URL=tcp://tasks.agent:9001) (err=Cannot connect to the Docker daemon at tcp://tasks.agent:9001. Is the docker daemon running?)

Afterwards it becomes, 5 minutes in between these errors:
cron error: endpoint snapshot error (endpoint=someHost, URL=tcp://tasks.agent:9001) (err=error during connect: Get https://tasks.agent:9001/_ping: dial tcp: lookup tasks.agent on 127.0.0.11:53: dial udp 127.0.0.11:53: socket: too many open files)

After 4 - 5 hours logs get flooded by this error, one line each second:
http: Accept error: accept tcp [::]:9000: accept4: too many open files; retrying in 1s

Error type 2 still comes up every 5 minutes.

Will try --no-snapshot as well.

Portainer seems to be running much more stable with the --no-snaspshot added. It's now up for 4 days without any issues!

The --no-snapshot flag is not a solution here, it was just used to isolate the cause of the problem.

I believe that #2235 solves this issue, waiting for some feedback from other users before we decide to merge it.

Hi there,
We have been able to reproduce this bug based on Premik's advice and instructions. Hopefully this will help us get to the bottom of this bug! Our reproduction steps are below.

Reproducing using a Stack file
Step 1: Spin up 2 Vagrant VMs to form a Docker cluster
Step 2: Connect to the manager node via ssh:
vagrant ssh swarmnode1
Step 3: Using our portainer-agent-stack file add the Agent and Portainer UI to the swarm

curl -L https://downloads.portainer.io/portainer-agent-stack.yml \
    -o portainer-agent-stack.yml 
docker stack deploy --compose-file=portainer-agent-stack.yml portainer

Step 4: Enter below commands suggested by Premik (we used /bin/sh instead of /usr/bin/sh)

sudo su
export p=$(docker  inspect --format '{{.State.Pid}}' $(docker ps | grep agent | cut -c-12))
yes 'ls /proc/$p/fd | wc -l; sleep 2' | /bin/sh

Every 2 seconds the number of pages loaded in the Agent will be displayed.

Step 5: Open the Portainer UI in the browser, create an account and navigate to the dashboard. Triggering the behaviour: Reloading the browser on the dashboard as well as switching between the dashboard and stacks should increase number of pages loaded by between 1&7 and will occasionally decrease by 1 before going up again.
Screen Shot 2019-03-19 at 7 16 44 pm

Reproducing as Separate Services
When deploying the Agent and the Portainer UI separately as services, this behaviour is repeatable.

Deployment commands:
Screen Shot 2019-03-19 at 7 16 59 pm

What doesn't work

  1. When the Agent and Portainer UI are deployed on a singular manager node using the stack file deployment used earlier this behaviour was not repeatable. (User Premik who suggested this method had the same behaviour on a single node.)
  2. When the Agent is deployed from a stack file saved on the vagrant vm using the CLI and the Portainer UI is deployed using the docker run command below, and Portainer is connected to the Agent endpoint, this behaviour is NOT repeatable.

We have done some further investigation into this issue.
The ever increasing fd behaviour is reproducible when executing GET requests to the following endpoints of the API, only after loading the Portainer dashboard for the first time. If you don’t physically load the dashboard in the browser first, get requests to the following endpoints won’t trigger the behaviour.


:9000/api/endpoints/1/docker/services
:9000/api/endpoints/1/docker/nodes
:9000/api/endpoints/1/docker/tasks
:9000/api/endpoints/1/docker/secrets
:9000/api/endpoints/1/docker/configs
:9000/api/endpoints/1/docker/info
:9000/api/endpoints/1/docker/swarm

Step 1: Follow the instructions in my previous comment for reproducing using a stack file. This will output the number of fd every 2s in your CLI
Step 2: Navigate to endpoint-ip:9000, create your user and navigate to the dashboard
Step 3: Refresh the browser
Step 4: Use the CLI or a tool like postman to complete get requests against one or more of the above endpoints

You should see the number of fd increase

Stopping the behaviour:


  • Step 1: Load the dashboard in the browser and refresh a few times to trigger the behaviour
    Step 2: Go to another view e.g services and refresh the page a few times and don’t go back to dashboard.
    Step 3: Execute one or more get requests against the above endpoints

You should now see this doesn’t increase the total fd. However loading the dashboard again and refreshing a few times will trigger it again

Other things we tried/discovered

  • If we took all the requests that the dashboard makes and executed them together in postman in the same order, this behaviour can be reproduced, only after first loading the dashboard. If you execute these requests, without first loading the dashboard, this behaviour will not be reproduced.


  • Swarm visualiser triggers this behaviour every 5s.
    Step 1: Log into Portainer in the browser and load the dashboard and make sure that the behaviour is triggered (if this hasn’t triggered the behaviour refresh it a few times and it should).

    Step 2: Enter the swarm visualiser, and now you will notice fd is incremented every 5 seconds

If swarm visualiser is left triggering this behaviour every 5s, then memory used by the agent slowly increases over time.

  • Following on from the above steps, enter the below command to output physical memory usage of the agent process every 2 seconds:
while [ 1 ] ; do
  grep VmRSS  /proc/$p/status ; sleep 2
done

Screen Shot 2019-03-20 at 12 43 50 pm

  • This behaviour can also be observed via the top command, the below value highlighted in red should keep increasing:

I've reproduced @itsconquest's result above, and discovered that the issue only occurs when I have non-master nodes in my cluster. I.e., I deployed 2 nodes using https://github.com/deviantony/vagrant-swarm-cluster (per the above instructions), and sure enough, the issue is present.

Then I promoted the worker node to a master, and redeployed portainer+agent. I was unable to reproduce the increasing-amount-of-FDs problem.

Once I demoted the worker node again, and redeployed, the increasing-amount-of-FDs problem recurred.

This might explain why the problem doesn't exist on a single-node swarm.
