Environment
Release : 16.0
Component : CA Top Secret for z/OS
Resolution
The U0753 abend occurred in CAKSMSERV at offset +x'3DC' with a
reason code 7.
This issue has been already seen in the past and for some undetermined
reasons and evidences due to a lack of appropriated clues and elements no
diagnostic could be done.
ENF calls TSS twice when CICS region starts and then ends up with an abend
and CICS can't start.
On next start, CICS region comes up and runs fine.
It has been noticed that this issue very rarely occurs and every time the
second CICS start is fine.
The paper dump does not contain the areas of storage that are needed to help us determine what is causing the error.
The only thing that can done is to set a slip trap in order to catch a system
dump on next occurrence as follows:
SLIP
SET,C=U0743,JOBNAME=cics_jobname,SDATA=(psa,csa,sqa,lsqa,sum,trt,rgn),ID=TSS,END
