If you suspect that there is a problem within the MVS™ system logger that is not a result of some other resolvable problem, you might need to collect additional diagnostic information.
The dumps generated by CICS® VR generally do not contain sufficient information about the MVS system logger.
DUMP COMM=(meaningful dump title)
R ww,JOBNAME=(IXGLOGR,XCFAS,CICSVR_jobname),DSPNAME=('XCFAS'.*),CONT
R xx,STRLIST=(STRNAME=structure,(LISTNUM=ALL),ACC=NOLIM),CONT
R yy,REMOTE=(SYSLIST=*('XCFAS','IXGLOGR'),DSPNAME,SDATA),CONT
R zz,SDATA=(COUPLE,ALLNUC,LPA,LSQA,PSA,RGN,SQA,TRT,CSA,GRSQ,XESDATA),END
Use the R xx,STRLIST=(STRNAME=structure,(LISTNUM=ALL),ACC=NOLIM),CONT instruction only where you suspect a problem with the coupling facility structure.
Error records written to the MVS LOGREC data set might also be useful
