PQ72513: ABEND SCC3 REASON CODE 040E0002 DURING APPSERVER STOP PROCESSING.

APAR status
Closed as fixed if next.

Error description
An ABEND SCC3 reason code RSN040E0002 occurs in a WebSphere for
z/OS J2EE server control region. The control region has just
scheduled an SRB over to one of its application server regions.
That SRB failed with an ABEND S0C4 reason code 11. This SRB
failure was reported to the control region after the IEAMSCHD
macro completed.  Register 0 in the SDWA for the SCC3 LOGREC
entry was 000C40000 and Register 2 was 00000011. The previous
LOCREC entry documented the S0C4 reason code 11 ABEND.
  The control region was processing a STOP request which could
have come either from the operators console or from the SMEUI.
It was scheduling "stop" SRBs to each of the active server
regions. At the same time, each of the active server regions
were being terminated with SEC3 reason code 04130001 which is a
TIMEOUT abend. By the time the "STOP" SRB started to run, the
server was dismantled far enough for some of the control blocks
including CPOOL blocks to be no longer backed. The control
region should not send "STOP" requests to server regions that
have already been told to stop for TIMEOUT reasons.
Local fix
This problem will only occur if STOP processing is initiated
while appserver regions are being terminated due to other
reasons such as TIMEOUT. Avoid using the stop command to end the
server while address spaces are timing out.

****************************************************************
As part of the processing of a stop command, an SRB is scheduled
to each server region.  However, if the server region has been
abended as the result of a timeout, then the SRB may ABEND0C4-11
trying to access control structures that have been removed by
server region termination processing for the timeout.  The SRB
abend is reported to the control region which takes the CC3
abend.  The control region should not attempt to stop server
regions it has abended for timeout.
Problem conclusion Temporary fix Comments
This APAR is being closed FIN with concurrence from the
submitting customer. A solution to this problem will be
delivered in a WebSphere Application Server for z/OS
and OS/390 release within the next 18 months.
