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.Problem summary **************************************************************** * USERS AFFECTED: All users of WebSphere Application Server * * V4.0.1 for z/OS and OS/390 * **************************************************************** * PROBLEM DESCRIPTION: An ABENDSCC3-040E002 can occur during * * stop processing for a control region if * * a server region associated with the * * control region is terminating due to a * * timeout at the same time. * **************************************************************** * RECOMMENDATION: * **************************************************************** As part of the processing of a stop command, an SRB is scheduled to each server region.

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.
