APAR Error Description / Circumvention

-----------------------------------------------
Possible hang during power down if service tools LAN adapter is
selected, but has no IP address assigned. Main storage dump
analysis showed deadlock between tall and short TCP stack
involving system job QTCPWRK waiting on a seize held by task
TONAMTASK.

CORRECTION FOR APAR MA43994 :
-----------------------------
A deadlock can occur if the "tall" stack (i.e. normal system
TCP/IP stack) and the "short" stack (i.e. service TCP/IP stack)
share the same adapter and the service stack is attempting to
activate a link-local IP address while the system TCP/IP stack
is ending. The PTF prevents this deadlock.

CIRCUMVENTION FOR APAR MA43994 :
--------------------------------
None.


Activation Instructions


None.




Special Instructions

THIS PTF CAN BE APPLIED IMMEDIATE OR DELAYED.
