Cause and solution:

The cause is a corruption of the file Mailbox.msg, probably because the file is not large enough for the number of messages that needed to be written to it.

Consider if it seems likely that the problem is caused by the file overflowing:
  • If you are sure that this is the cause, you can delete the corrupted message file.

    All events lost: Following this procedure means that all events in the corrupted message file are lost.

    Perform the following steps:
    1. Use the evtsize command to increase the Mailbox.msg file. Ensure that the file system has sufficient space to accommodate the larger file.
    2. Delete the corrupt message file.
    3. Restart IBM Workload Scheduler by issuing the conman start command on the fault-tolerant agent.
