We have rolled out a fix and are currently monitoring the result.

Any nodes still in Kill Task Fail will need to fully drain of running jobs first before being reopened to ensure there are no orphaned processes.
PLEASE NOTE: This will take quite some time to fully resolve as jobs are still running on these nodes. But the nodes cannot accept new jobs until cleared.
Currently # of potentially impacted nodes: 523 (of an original 600 - number will update periodically)

We are currently investigating this incident. Due to a CVMFS mount issue, some nodes are being closed and labelled as "Kill task fail"
