             Summary: Jenkins leaves behind connections in ESTABLISHED state
                 Key: OVIRT-729
                 URL: https://ovirt-jira.atlassian.net/browse/OVIRT-729
             Project: oVirt - virtualization made easy
          Issue Type: Bug
            Reporter: Evgheni Dereveanchin
            Assignee: infra
            Priority: Low


Throughout the last days I noticed several times when a slave got non-responsive and after rebooting it never recovered until being removed/re-added to Jenkins.

Further investigation on el7-vm06.phx.ovirt.org revealed that on Jenkins the connection is still marked as "ESTABLISHED" hours after the slave crashed and rebooted:

tcp6       0      0 66.187.230.92:33374     66.187.230.77:22        ESTABLISHED 14625/java 
{quote}

Due to this new SSH connections are not opened and Jenkins can't reconnect to the slave.
I didn't see this behavior before, maybe it is related to the latest security upgrade of jenkins.
