PSLOCK is occurring when running Search/Match/Post (SCC_SL_SMP) process.

PSLOCK issue appears to be stemming from the 'save' call in app class SCC_SL_TRANSACTION:ACCESSORS:StagedUserPerzCategory, which issues the following SQL:

This is a PeopleTools table, and tools internally serializes its updates via the PSLOCK table using object type names = 'UPM' and 'SYS'.  Although PSLOCK is being updated when the rowsetcache objects are being refreshed, this only happens the first time they are used. After that, they
stay in the rowset cache, and this does not trigger updates to PSLOCK.
