Upgrading a PANLIB some users have experienced the following error:
+PV999 *PANVALET INTERNAL ERROR
IEF450I PANGPM4 HISTORY PAN2DHSX - ABEND=S000 U0222 REASON=00000000 069
***** PROTECTION FILE I/O MANAGEMENT LOGIC ERROR, CODE=209 - FRAME(OUT):
FRAME/BUFFER OVERFLOW* ERROR MESSAGE = PV093 *
The resolution to this problem is usually to backup and restore the PANLIB.
This is an old 14.3 bug fixed by LO32480. If the bug in the PANLIB wasn't it wasn't resolved by a backup under 14.3 after LO32480 was applied, it surfaces later. r14.3 fix LO32480 is incorporated into later releases, so a 14.5 backup and restore cleans it up.
If the backup and restore doesn't resolve it, then try reblocking the PANLIB.
If that doesn't work, then please open an issue.
