Much more information is needed to investigate further. Start by including the full error message and stack trace if present, as well as any possibly relevant log messages.

Thanks Daniel , I just added the master & slave logs

just add the log files

This is pretty insane. Doesn't look like a bug though. I'd investigate whether your network has issues. Use of WiFi, routers that drop connections, broken cables, etc.

You could try opening a basic network connection (e.g. telnet) between slave and Jenkins master. If that goes down at the same time, it's unrelated to Jenkins.

Use of Wireshark may also help.

Hi Daniel
Thanks for your help , I already asked the IT team to monitor the network , they didn't find any error ...

I think that maybe one of the plugins cause this error , but must say that I don't have a clue.

I just removed one of the plugins that had a lot of exceptions to clean the log file , so it will be easy to read it.

the strange thing is that when the same tests run with a MVN step , it failed much more , and I don't have a clue for it.

Thanks , Mor

Any update on this issue? I've been facing it as well.... was wondering if there is some king of solution?
Any chance it's related to the ping mechanism? I'm going to try and disable it and see if it helps.
Any help would be greatly appreciated.

Thanks!
Dvir

The same error is here also: https://issues.jenkins-ci.org/browse/JENKINS-28155

I am seeing the very same error on Windows slaves, no OS X or Linux slave shows this. The weird thing is that the next build runs fine on the node, right after the 'apparently' failure.

Finished: FAILURE

Experiencing the same problem. Also as mentioned earlier, I have almost always seen the build succeed on the next attempt. The master in this case is on Linux and the slave is a Windows build server.

I'm having problems since last friday 10-06-2016, I did an update to jenkins 2.7 just before
I have a long running job which needs to run for aprox 2 hours.
It went down 2x after 24 minutes. What is weird is that it fails on day 1, then on day 2 it went ok and it fails again on day 3. As expected it worked again last night (day 4).... So I'm curious if it will fail tonight. I will wait with updating Jenkins to 2.8 untill tomorrow to at least see what happens tonight.

UPDATE: Jenkins didn't fail last night. I will upgrade to 2.8 now and monitor it for a couple of days

@Jan Saris, Any update on 2.8?

@Sharan Math, I upgraded to 2.9 and the build is now stable for a week (1 job every night).

It was likely SocketTimeoutException on the slave side in this case (fixed in 2.60 & released in 2.9).
In order to confirm it, it would be useful to have a log from the slave side.

TL;DR I'm having this issue on windows with slave 2.62.2 and server 2.34. Right now it's with every build

nerumo Could you please provide logs from both master and agent sides?

Hi
jenkins.4.err.log jenkins-slave.5.err.log
It was on the 30.Nov 10:30pm. A little bit more to the setup. I have a master in the cloud and 3 slaves behind NATs.
I never changed a default configuration of the slave or the master about how the connection should be established. Whats the best configuration for my scenario anyway?
Thanks

Unfortunately I have no capacity to work on Remoting in medium term, so I will unassign it and let others to take it. If somebody is interested to submit a pull request, I will be happy to help to get it reviewed and released.
