I found these in the archives, they seem to be relevant:

I'm guessing that it was MCH3402:
 "Tried to refer to all or part of an object that no longer exists."

When you have a service program running in ACTGRP(*CALLER) that's called
from the default activation group, RCLRSC will close that service
program's files, but not reset anything in the service program itself, or
even notify the service program that something has changed.

When you call the service program (which is still loaded, since RCLRSC
does not remove ILE objects from memory unless their set to
DFTACTGRP(*YES)) it tries to access it's file and them BOOM!
