Brian Harris commented on JENKINS-12235:
----------------------------------------
For us, the cause of this error was our build slaves (VMs) running out of
memory and self-rebooting.
> FATAL, Unable to delete script file, IOException2, remote file operation
> failed, unexpected termination of channel

> Key: JENKINS-12235
> URL: https://issues.jenkins-ci.org/browse/JENKINS-12235
> Project: Jenkins
> Issue Type: Bug
> Components: core, master-slave
> Reporter: Ghenadie Dumitru
> Attachments: jenkins_fatal_io_exception.txt, stacktrace.txt
>
>
> Below is the stacktrace.
> It happened when I ran two jobs on a master. After running a while, both jobs
> crashed with this exception.
> I think this might be caused by a small flip-flop connectivity of the
> network, but I didn't noticed any disconnection.
> Another cause may be the huge load of jenkins:
> PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND

> Does the jenkins runs its own garbage collector at some specified time?
> We have to restart every few days because it's getting slower and slower
> until hangs out.
