An abend occurred while the Monitor III data gatherer enqueue event handler module (ERB3GEEH) was processing. ERB3GEEH receives control from ERB3GLUE. ERB3GLUE is invoked when enqueue contention in the system changes. The internal FRR recovery routine GEEHFRR requests an SVC dump. The areas dumped are TRT and SUMDUMP. The SUMLIST option specifies the ERB3GEEH module work area and the enqueue event table entries.
