Purge user with Force causes Switch abend

Q:

Is it true if a logical terminal is forced inactive (PURGE user,FORCE) it will cause VTAM/Switch to fail?

A:

Yes, the "PURGE user,FORCE" option can cause VTAM/Switch to ABEND. It should only be used as a last resort as it bypasses integrity checks. If the FORCE option is used and VTAM/Switch does not ABEND, VTAM/Switch should be SHUTDOWN and re-started at your earliest convenience.
