Error description

  • Crash occurs in
    BBOG_FailureMonitor::dispatchRecovery(MVS::STOKEN) in a control
    process following a stop command being issued for the server.
    
    
    The problem can be seen in the dump as an abend0c4 at
    BBOG_FailureMonitor::dispatchRecovery(MVS::STOKEN) +13E
    or as
    an abend0c1 in destructors like
    
    ORBR_GTIDCollisionElement::¯ORBR_GTIDCollisionElement()
    or
    Snoozer::¯Snoozer()
    when called on the path from
    BBOG_FailureMonitor::dispatchRecovery(MVS::STOKEN)
    
    The failure
    happens because an object was deleted and reallocated as
    something else.
