  • Files that are still referenced are deleted
  • Logs of the two jobs are mixed up
  • In BackgroundMethodServer, it appears that two job threads wrote something to the same file:
[RemoveUnreferencedTaskQueue.PollingThread] wt.system.out administrator - Writing to file /apl/Windchill_10.1/Windchill/tmp/ReferencedFiles
[AutomaticVaultCleaner.SchedulingThread] wt.system.out administrator - Writing to file /apl/Windchill_10.1/Windchill/tmp/ReferencedFiles
