![]() APAR status Closed as program error. Error description Abend 0C4 in BBOCOMM during normal server execution due to a zero pointer. The traceback for the thread that 0C4ed: SessionBucket::addToSessionCollisionQueue(Session*) SessionManagerProtocolHTTP::processAsynchIOAccept(AsynchData SessionManager::processAsynchIOAccept(acrwObj*) ACR_ExecutionThread::RemoveAndProcessWork(ThreadCleanUp*) ACR_ExecutionRoutine The zero pointer was because part of the storage was overlaid with 0s. This was caused by a thread that was doing MVC (coping session object) for a length of FFFFFFFE (-2). The invalid session length was caused by a bad parsing of the session cookie. The thread that caused an overlay has the following traceback: HTTP_Request_Parser::processCookies(HTTP_Request_Parser::met Server_HTTPSession::read_msg(SEQUENCE_octet**,unsigned long* HTTP_Request::http_inbound_request(ORB_Request*,acrwObj*) ORB_Request::comm_HTTP_inbound_request(acrwObj*) ACR_ExecutionThread::ProcessHttpInboundRequest(acrwObj*,Thre ACR_ExecutionRoutine In addition, syslog was filled with many page fault entries for the above thread: 01 01FC 009DD088 PGM 011 072C2000 9C797252 00060011 00000000 1E10A000 01 01FC 009DD088 PGM 011 072C2000 9C797252 00060011 00000000 1EF9E000 01 01FC 009DD088 PGM 011 072C2000 9C797252 00060011 00000000 1E10B000Local fix Problem summary **************************************************************** * USERS AFFECTED: All users of WebSphere Application Server * * V5.0 for z/OS * **************************************************************** * PROBLEM DESCRIPTION: ABENDS0C4 in the Websphere Application * * Server Controller. * **************************************************************** * RECOMMENDATION: * **************************************************************** A parsing error with the HTTP Transport causes a storage overlay.
