Error description
In a mixed cell environment with Daemon at V7 of WebSphere Application Server, and Node at V6.1, a V6.1 application server servant region (SR) may terminate unexpectedly with abend S0C4. This problem is more likely to occur during STOP processing of the server, but it could also occur during normal server runtime. In the reported case, a TDUMP was taken for the 0C4 abend. The failing thread had the following traceback: Native traceback: _TDUMP j9dump_create doSystemDump protectedDumpFunction j9sig_protect runDumpFunction triggerDumpAgents dumpCrashData j9sig_protect structuredSignalHandler masterSynchSignalHandler __zerro __zerros CEEHDSP CEEOSIGJ CELQHROD CEEOSIGG CELQHROD CurrentRequestLanguage::btcb_Java_RMI_On() Java_com_ibm_ws390_orb_ClientDelegate_createRequestCFW RUNJAVATHREAD javaProtectedThreadProc j9sig_protect javaThreadProc thread_wrapper CELQPCMM Java traceback: com/ibm/ws390/orb/ClientDelegate.createRequestCFW com/ibm/ws390/orb/ClientDelegate.createRequest com/ibm/ws390/orb/ClientDelegate.request org/omg/CORBA/portable/ObjectImpl._request ObjectImpl.java:458 com/ibm/ws/management/_ControlAdminService_Stub.handleServantNot ifications _ControlAdminService_Stub.java:247 com/ibm/ws/management/event/PushToControlNotificationSender.hand leNotifications PushToControlNotificationSender.java:93 com/ibm/ws/management/event/PushRemoteSender.pushNotifications PushRemoteSender.java:56 com/ibm/ws/management/event/AbstractPushRemoteSender.alarm AbstractPushRemoteSender.java:191 com/ibm/ejs/util/am/_Alarm.run _Alarm.java:90 com/ibm/ws/util/ThreadPool$Worker.run

Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere Application Server * * V7.0 * **************************************************************** * PROBLEM DESCRIPTION: ABEND0C4 occurred in WebSphere * * for z/OS Application Server Servant * * Region when running in a mixed * * cell environment. * **************************************************************** * RECOMMENDATION: * **************************************************************** The servant (SR) is running daemon level code for its Task related recovery code. The size of a task related piece of storage has changed between the daemon level of code and the node level of code. The storage is internally called the TRDI (bbootrdi.mac). In the SR, the node level of code obtains and initializes the TRDI, but the daemon level of code releases the TRDI. This resulted in releasing more storage than was intended, and corrupted structures in the related storage. This caused the ABENDS0C4 in CurrentRequestLanguage::btcb_Java_RMI_On() which attempts to write into the TRDI. Also, to confirm this problem, ABEND378 REASON=24 abends have been observed in the LOGREC.
Problem conclusion
Code has been modified in the servant environment to use the node level of code for task recovery. APAR PM04574 requires changes to documentation. NOTE: Periodically, we refresh the documentation on our Web site, so the changes might have been made before you read this text. To access the latest on-line documentation, go to the product library page at: http://www.ibm.com/software/webservers/appserv/library The following changes to the WebSphere Application Server Version 7.0 Information Center will be made available in June, 2010. The table "WebSphere Application Server for z/OS abend codes" that is contained in the topic "Abend reason codes" will be updated to include the following new EC3 ABEND reason code: Abend Code Abend Reason Explanation Suggested Action EC3 04010011 Internal IBM Internal Only product error APAR PM04574 is currently targeted for inclusion in Service Level (Fix Pack) 7.0.0.11 of WebSphere Application Server V7.0 Please refer to URL: //www.ibm.com/support/docview.wss?rs=404&uid=swg27006970 for Fix Pack availability.
