Are you SMS-caching the PDSE?  See APARS II14026 OA15322 for hints.

Subject: VLF Question


I have a situation where there are high "EXCP" counts against a PDSE 
STEPLIB, but a GTF trace of the target volume shows no actual I/O. Does
anyone know whether VLF accumulates "fake" EXCPs, perhaps to 
reflect what would be the case if it (VLF) wasn't active?

Thanks,
Art
