NOTICE:

Application of this PTF may disable or render ineffective programs that
use system memory addresses not generated by the IBM translator,
including programs that circumvent control technology designed to limit
interactive capacity to purchased levels.  This PTF may be a prerequisite
for future PTFs.  By applying this PTF you authorize and agree to the
foregoing.

This PTF is subject to the terms of the license agreement which
accompanied, or was contained in, the Program for which you are obtaining
the PTF.  You are not authorized to install or use the PTF except as part
of a Program for which you have a valid Proof of Entitlement.

SUBJECT TO ANY WARRANTIES WHICH CAN NOT BE EXCLUDED OR EXCEPT AS EXPLICITLY
AGREED TO IN THE APPLICABLE LICENSE AGREEMENT OR AN APPLICABLE SUPPORT

APAR Error Description / Circumvention

-----------------------------------------------
Occasionally, when a process is spawned by an API, command, or
other system function, the spawning process may hang or the
spawn operation will fail. Error numbers 3021 (EINVAL) or 3474
(EUNKNOWN) may be associated with the failures.

CORRECTION FOR APAR SE73266 :
-----------------------------
Spawning a process allocates resources that are shared between
the parent and child processes. These resources are not always
managed properly. The PTF corrects the problem.

CIRCUMVENTION FOR APAR SE73266 :
--------------------------------
None.


Activation Instructions


This PTF contains objects that are activated only at IPL time.
Therefore, if this PTF is applied as an immediate PTF, you must
perform an IPL of the system to activate the PTF. Applying the
PTF as an immediate PTF will ensure that the PTF becomes active
even after an abnormal IPL where delayed PTFs are not applied.

If the PTF is applied as a delayed PTF, no further action is
necessary.





Special Instructions


None.


Default Instructions

THIS PTF CAN BE APPLIED IMMEDIATE OR DELAYED.
