BPXM056E

Explanation
 The system detected a z/OS® UNIX System
Services latch contention situation that has existed for an excessive
amount of time. As a result this task is not progressing as expected
nor are the tasks waiting on the held resources.

System action
 Processing continues, and latch contention continues
until the operator or system programmer take action to relieve the
latch contention situation.

Operator response
 Notify the system programmer.

System programmer response
 Issue the D GRS console command to
gather information regarding the latch resource, latch owner(s) and
latch 			waiter(s).  If the contention persists and the owning unit(s)
of work cannot be terminated through normal operations (for example,
Cancel or Force commands), consider issuing a F BPXOINIT,RECOVER=LATCHES
 console command to resolve the contention. This command can take
several minutes to resolve the latch contention, but if MVS™ cannot resolve the latch contention within
a reasonable time interval, MVS eventually
displays action message BPXM057E. If necessary, refer to that message
for further action. Note: If successful, the F BPXOINIT,RECOVER=LATCHES
command causes the abnormal termination of user tasks holding latches,
generates one or more address space dumps, and can result in the termination
of an entire process. Refer toz/OS MVS System Commands before
issuing this command.
