If you specify the HOLD option on your LOGOFF / DISC command: LOGOFF HOLD -- or -- DISC HOLD
do the symptoms change at all?
To quote from the HELP ...
HOld
causes the non-SNA TTY display terminal telecommunication connection
to
remain in effect after your session is disconnected. If you specify
the
HOLD option from a logical device, you disconnect from the logical
device
without losing the connection between the logical device and the
system.
