- Was involved in either a deadlock or lock timeout. 
- The instance was running low on MON_HEAP storage (which is 
used to allocate fast writer records). 
- Activities were to be recorded in deadlock or lock timeout 
events because the database config has HISTORY specified for 
both mon_deadlock and mon_locktimeout:
