Error description

  • You have tasks waiting for file buffers, resource name FCBFSUSP.
    During CICS shutdown, a CESD task issues a forcepurge for each
    of these tasks. But before these tasks get a chance to be
    dispatched and start purging, DFHFCVS, proc BUFFER_RELEASE,
    issues RESUMEs for all of these tasks while executing on behalf
    of another task that was terminating and so freeing the buffer.
    As each of these tasks gets dispatched, they get a PURGED
    response (due to the CESD purge), and so now a second RESUME is
    issued. This will cause the CICS Dispatcher to subsequently
    issue the error:
    .
    DFHDS0002  A SEVERE ERROR (CODE X'0056') HAS OCCURRED IN MODULE
               DFHDSKE.
    .
    The trace shows an accompanying exception entry:
    .
    DS 0056 DSKE  *EXC* - DSKE_TASK_SUSP_TOK_IN_USE
    .
    The problem is very similar to PK86217 except that the tasks
    here are waiting on file buffers, not exclusive control
    conflicts.

    ****************************************************************
    DFHDS0002 A severe error (code X'0056') has occurred in module
    DFHDSKE is issued, along with exception trace entry:
    DS 0056 DSKE  *EXC* DSKE_TASK_SUSP_TOK_IN_USE.
    If a task is waiting in File Control for a VSAM Buffer then it
    may time out and be resumed by another task. A purged or timed
    out response at this point will cause a resume to be issued. The
    double resume can cause problems later, for instance the next
    suspend may be resumed immediately.

Problem conclusion

  • DFHFCVR has been amended to ensure a resume is only issued
    after a purged response if the task has not already been
    resumed by the task that was holding the resource.
