Good old ASRBULCH latch. First of all, make sure you have all the required maintenance for PDSE on (there are several apars involving ASRBULCH out there, and this appears to be an ongoing bug that IBM seems unable to fix). > VARY SMS,PDSE1,FREELATCH(000000007FF67610,006A,00AFF208),RETRIES(5) > IGW032I PDSE FREELATCH Start of Report 889 > ++ Free latch failed latch:7FF94DD8 is either broken or not a latch > PDSE FREELATCH End of Report In my case (we had it twice) it was not obvious which latch to free (there were tons of ASRBULCH ones). So I went through all of them and eventually found the one that was left and had caused everyone else to back up. In that process, I also generated some PDSE abends complaining about freed latches. By the way, even forcing the address spaces will not clear the contention! Admittedly, I have never seen the response of 'either broken or not a latch'. That sounds like something went ahead and freed the storage where the latch is situated. I have heard from our customers (who were also affected for a library that is NOT in linklist) that restarting SMSPDSE1 did not free the latches. The customers affected by it were also able (with trial and error) to use freelatch. If that library SYSVIEW.R137.CNM4BLOD.SYS1 is not a load library (or anthing else that *requires* it to be a PDSE) then I suggest to make it a PDS to avoid hitting PDSE code. If you have the appropriate contract with IBM, when this hits next, then take a dump of the address spaces involved in the latch contention and SMSPDSE/1 and report the bug to IBM.
