In the first week of last December our operations team called us with an auxiliary storage shortage on one of our systems, where SMSPDSE1 was occupying about 70% of auxiliary storage. To resolve this situation we restarted SMSPDSE1. We then went over the SYSLOG and OPERLOG and discovered that SMSPDSE1 was stuck in some sort of a recovery routing loop for almost 24 hours, writing OPERLOG records every time and apparently allocating some storage without releasing it. What triggered this was the abends described in OA35260 and OA35296 which occurred the night before, when our HSM migration was running. After the abends, both HSM and SMSPDSE1 kept running "normally".
We opened a PMR about this problem and are running with a SLIP trap requested by media manager support and PDSE level 2 since then. So far the abends haven't happened again though. As Brian mentioned, we applied these PTFs as part of our regular RSU maintenance... We are now looking into backing off these PTFs, as we really don't want to disable zHPF... Gil.
