APAR PK10591 describes an overlay which occurs when a user (or job, or started task) attempts to use TCP/IP's RESOLVER service without an OMVS segment - either an explicit one, or a system-wide default OMVS segment.
If this unfortunate circumstance occurs, RESOLVER can overlay field UCBNXUCB. According to the APAR text, FDRPAS uses UCBNXUCB. I don't have FDRPAS, but followed the "VERIFICATION STEPS" in the APAR, and discovered that four DASD UCBs have been overlayed on my system. We do not have a default OMVS segment defined, so I suspected that we would be exposed to this problem. The defect apparently exists in z/OS 1.6 and higher. There have been no ill-effects noticed on my system, but I'm going to apply the fix asap, anyway - my assumption is that any UCB overlay cannot be a good thing.
