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.
