Error description

L3 analyzed the symtom and provided the comment below.
"Based on the fact that shutting down PA with the "-option
STOP" will also stop managed processes, and based on the
location of the thread in the core (sending a GW watch to the
ObjectServer) I suspect the ObjectServer has exited before the
gateway had a chance to send its GW watch, and the connection
was marked dead but not handled correctly in doing so,
resulting in the crash.
 Based on the code, it looks like the session being used is
garbage, so the pointers being used are invalid. This will be
the result of the session being de-allocated and the memory
reused, and so filled with garbage as far as session data is
concerned. It is noted in the code that a GW watch is being
sent when the backup ObjectServer connection is lost, but with
no primary connection to send it to (which is also lost) the
result is this crash.
This is definitely a bug, but the consequences are minimal in
the circumstances, as it appears everything is being shut down
anyway."
