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.
