Error description

  • ABN=074-00000000,U=SETUP   -CSQSGSTK,  M=CSQVLFRR
    is occurring when CSQSVSTK has issued a SETLOCK OBTAIN,TYPE=CML
    
    ABEND074 means a program issued the SETLOCK macro and
    supervisor control could not finish processing the macro.
    
    ST REGs and the SYSTRACE show the abend is actually an ABENDAC7
    RSN00440004. Reason 00440004 is because DIAGxx trap
    IEAMISUSEPMC is set to detect the misuse of "Process Must
    Complete". So, if a PAUSE is attempted with PMC set, ABENDAC7
    RSN00440004 is issued. SYSTRACE shows a SCHEDULE from CSQVEUS1
    before the abend SVC D. TCBPMC is no longer set at the time the
    TCB is captured however.

    ****************************************************************
    An ABENDS074 occurs after CSQSVSTK has issued a SETLOCK
    OBTAIN for a CML (Cross Memory Lock) while PMC (Process
    Must Complete) is in effect.
    The lock is currently
    held by another process, so a IEAVPSE (Pause) is issued to
    wait for it to become available. However this is an illegal
    command when PMC is set.
    This causes an Abend AC7-00440004. Since the IEAMISUSEPMC
    diag trap was set at the time of the abend, this produced
    the ABENDS074.
    

Problem conclusion

  • CSQVEUS1 has been altered to reset the PMC status before
    releasing the latch.
