This is the only occurrence of this abend and it only occurred in one region. Do you have any information as to what may have caused this abend?
I attempted to perform some searches on your website for this issue but found nothing. If you need anything else please let me know.

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
