Bug description

NetData agent that reports offline and then back online but only that server...

The server does not reboot except on Sundays and the link is dual 10GB LACP 802.3AD on Linux Alma 9.

This said it's been bothering me and unsure what to dig for more.

Screenshot

Screenshot_20240515-100008

With the help of Hugo Valente on the Discord we discovered :

there is a SIGTERM error that then unleashes the shutdown of the Agent, including ACLK and so the connection to Cloud

May 15 04:07:56 srv-duplicacy.shedmtl.local netdata[2402999]: Shutting down command server.
May 15 04:07:56 srv-duplicacy.shedmtl.local netdata[2402999]: SIGNAL: Received SIGTERM. Cleaning up to exit...

Expected behavior

No crash or reboot of the agent.

Steps to reproduce

  1. Install AlmaLinux 9
  2. Configure network with dual 10GB 802.3ad with LACP on switch side.
    3.Install NetData agent and bind to cloud.
    ...

Installation method

kickstart.sh
