I see no holders, I would suggest taking what IPCS ANALYZE says about locks with several grains of salt for a dump which is not a standalone dump. It is not be possible to be suspended for a lock while holding the CPU lock. I do not understand what you mean by "a hard loop trying to get a CML lock." If a program is looping doing a SETLOCK OBTAIN,TYPE=CML,MODE=COND,etc, that would generally be a bad idea. Jim Mulder z/OS System Test IBM Corp.
