After aborting the build. The build fails with this error. So, it basically stuck at a post build step of copy artifacts

I had the same problem after a server restart. I don't exactly know the cause, but I managed to solve it by stopping the service (on win) and removing the workspace and tools folder from the jenkins slave. After a restart of the slave everything seems to work again.

I am experiencing something similar which I posted here:
https://issues.jenkins-ci.org/browse/JENKINS-20986

I also saw these "Failed to monitor <CHANNEL_NAME> for Free Swap Space" but since this was just category "Warning" I dismissed this.
But in my case, the job also appears to hang at the "Archiving artifacts" stage and when I check the logs it says:

"SEVERE: I/O error in channel <CHANNEL_NAME>
java.io.IOException: Unexpected termination of the channel"

It appears to terminate the channel when it should collect the artifacts. Via ssh my channel automatically reconnects but after that the job will still hang at the "Archiving artifacts" stage until I manually abort it.

My older Jenkins install version 1.431 does not have this problem. There, the jobs can archive their artifact when using this exact slave. So I figure it must be a Jenkins problem itself rather than a slave problem. The slave works fine for an older jenkins install but a newer Jenkins install (version 1.509.4 LTS) has this problem.

I am running also massively into this issue rearding running VM's on demand which run slaves. More Information see attached PDF file 'MonitorFreeSwapSpace.pdf'

For me this behaviour is critical because, the slave doesn't work anymore.

Andreas: The warnings have almost surely nothing to do with your slave connection problems. Looks more like JENKINS-22932.
