APAR Error Description / Circumvention

-------------------------------------------------
The ASCL-FAXLINE13 task halted the system after a LIC module
locked a gate and then tried to unlock the gate, but the gate
storage was corrupted. LIC log shows VL 1000220C shortly before
the halt, and the PAL has lots of B600FDC0 entries.

CORRECTION FOR APAR 'MA48112' :
-------------------------------
The 1000220C LIC log entry indicates that storage was deleted
twice. This occurred due to a timing window when ending the
ASCL-FAXLINE13 task. The FDCO PAL entries indicate that multiple
Fax lines were unable to establish a connection and are
unrelated to this problem.

This fix corrects the timing window when ending the task and
prevents storage from being deleted twice.

This problem can only occur on a system that has an Async or PPP
line description that is configured with RSRCNAME(*ETHDEVSVR).
The problem can occur when the Async or PPP line is varied off,
or when the Async or PPP line goes through error recovery.

CIRCUMVENTION FOR APAR 'MA48112' :
----------------------------------
None.


Activation Instructions
