IV53262: PRIOR INSTANCES OF DAPLI_THREADS MAY PROCESS CURRENT EVENTS

A fix is available

 

APAR status

  • Closed as program error.

Error description

  • The current instance of dapli_thread may be hung because some
    other instance of dapli_thread from the past (which hasn't been
    cleaned properly) may reap its event. As a result the cyrrent
    dapli_thread may be stuck in a sleep waiting for an (async)
    event for which it was woken up (but which has since been
    processed by the other instance).
    

Local fix

Problem summary

  • The current instance of dapli_thread may be hung because some
    other instance of dapli_thread from the past (which hasn't been
    cleaned properly) may reap its event. As a result the cyrrent
    dapli_thread may be stuck in a sleep waiting for an (async)
    event for which it was woken up (but which has since been
    processed by the other instance).
    

Problem conclusion

  • The uDAPL thread (dapli_thread) wasn't being cleaned up
    properly The solution makes sure that, upon close, the
    dapli_thread falls through and is done... that will ensure that
    these threads won't hang around and the current events are
    received only by the current threads.
