A spontaneous problem with Cloak-TCP (caught a crash log this time) #230
Comments
|
That's coming from deep in golang runtime, not from cloak itself, it might a bug there (very low probability), or you may have some kind hw issue (maybe too aggressive overclock or failing ram ?) |
|
Well, I can't really positively rule it out since it's a small "industrial" unit with SSD being the only user replaceable part When the job is done I may run some stress tests on it later but the only thing it is doing is being a gateway and cloakifying a particular TCP connection so it isn't under huge big load. |
|
@notsure2 for what it's worth I've been able to produce very similar crash behavior on a rather well maintained laptop with fresh Qubes install by simply letting TCP shadowsocks "hard stall" and then not touching it for like two hours or so Thus unlikely to be hardware fault (well, two different machines may have both have subtle hardware problems that manifest similarly, but unlikely) |
|
checkdead is the golang deadlock detector. it crashes the process if it finds that no goroutines are running. It could be a real deadlock in cloak or an incorrect deadlock detection due to no data passing. I'm not sure. |
|
Well one thing I am certain of is that the software on the user side of Cloak client that crashed was desperately trying to send some data :-) |
So long story short I have a machine in adversarial conditions using Cloak TCP
Periodically, Cloak crashes like this :
runtime: checkdead: find g 99 in status 1
fatal error: checkdead: runnable g

The config is :
{
"Transport": "direct",
"ProxyMethod": "socks5tcp",
"EncryptionMethod": "aes-128-gcm",
"UID": "omitted",
"PublicKey": "omitted ",
"ServerName": "console.aws.amazon.com",
"CDNOriginHost": "console.aws.amazon.com",
"NumConn": 4,
"BrowserSig": "chrome",
"StreamTimeout": 300,
"KeepAlive": 299,
"LoopbackTcpSendBuffer": 5120,
"LoopbackTcpReceiveBuffer": 5120
}
The reason for using keepalives is that I have found this value of Keepalive to be substantially protective against stalls (related issue) (1 severe stall per multiple hours versus one per hour or more)
Hope this will help improving Cloak :-)
