BPXM123E

Explanation
 z/OS® UNIX processing has detected a potential
latching problem. A UNIX System
Services GRS latch has been held (without contention) by the specified
job for an extended period of time.
 In the message text: jjjjjjjj
The name of the job that holds a UNIX System
Services GRS latch.

System action
 None.

Operator response
 None.

System programmer response
  If the JOB listed in the message text is UNKNOWN, then
the job that obtained the latch is no longer active. This may indicate
an application error. If contention develops for this latch, it will
eventually be cleaned up and no intervention is necessary 
 If the JOB listed is something other than UNKNOWN, issue
the D GRS,LATCH,JOB= command to gather information regarding which z/OS UNIX latch
the job owns. For a latch in the SYS.BPX.A000.FSLIT.FILESYS.LSN or
SYS.BPX.A000.FSLIT.FILESYS.LSN.xx latch set, issue the D OMVS,WAITERS
command for additional information about the latch. Collect  
LOGREC,
SYSLOG, and a CONSOLE DUMP of the ASID associated with the JOB holding
the latch, the zFS address space, the OMVS address space, and the
OMVS dataspaces.If it is determined that the latch is being held
in error, use the CANCEL command to attempt to free it.
 Note: Some jobs cannot be cancelled, for example OMVS and BPXOINIT.
Some jobs provided services to many users (servers). Consider
the impact of cancelling those types of job before using the CANCEL
command.
