APAR Error Description / Circumvention

-----------------------------------------------
TCP interface is unusable after network problem. QTCPWRK job
still shows active, but can't be ended. MSD analysis shows the
QTCPWRK job waiting on a gate held by an SK-ASC task that is
waiting on a WaitList.

CORRECTION FOR APAR MA46382 :
-----------------------------
A deadlock was occurring in a small timing window where the
connection Netstat was working on was also being accessed by
Telnet to send a Telnet session reject message. The deadlock has
been removed.

CIRCUMVENTION FOR APAR MA46382 :
--------------------------------
None.


Activation Instructions
