I don't know anything about the guts of CAS4PAS.  If you think this is a
bug in the sessioning machinery itself, you might try swapping out an
alternate session data manager, e.g. 'faster':

If that makes the problem go away, thenn you could work on trying to
reproduce the problem in isolation.  If not, then the bug is in the
CAS4PAS code itself.
