Error description
WebSphere MQ channels terminated unexpectedly with messages AMQ9604: Channel terminated unexpectedly and AMQ9208: Error on receive from host xxxxxx EXPLANATION: An error occurred receiving data from xxxxx over TCP/IP. This may be due to a communications failure. ACTION: The return code from the TCP/IP (read) call was 104 (X'68'). . The FDC's show that rriAcceptSess calls are failing in the amqrmppa process with a SIGSEGV and we are getting probe id's XC130003 and RM031101. The function stack for both FDCs shows: MQM Function Stack ccxResponder rrxResponder rriAcceptSess xcsFFST

Problem summary
**************************************************************** USERS AFFECTED: This problem may be encountered when attempting to connect to a queue manager which has channel auto-definition set (the queue manager CHAD attribute set to ENABLED). Users with channel auto- definition enabled are recommended to disable it if it is not required; or else to ensure a fix for this APAR is applied. Platforms affected: All Distributed (iSeries, all Unix and Windows) **************************************************************** PROBLEM SUMMARY: The SIGSEGV FDCs in amqrmppa show that function rriGetChannelDef (called from rriAcceptSess) invoked lpiSPIKernel which returned arcE_OBJECT_NOT_FOUND (it did not find the requested channel). Routine rriGetChannelDef should have returned a failure code, but it returned OK. This immediately leads to a SIGSEGV in rriAcceptSess. Very careful examination of the code of rriGetChannelDef reveals that there is a failure path out of this function whereby it fails to set its return code correctly.
Problem conclusion
Corrected the coding to ensure that all exit paths out of function rriGetChannelDef set a return code appropriately. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: v6.0 Platform Fix Pack 6.0.2.5 -------- -------------------- Windows U200292 AIX U815929 HP-UX (PA-RISC) U815636 HP-UX (Itanium) U815818 Solaris (SPARC) U815659 Solaris (x86-64) U815928 iSeries SE32853 Linux (x86) U815767 Linux (x86-64) U815808 Linux (zSeries) U815805 Linux (Power) U815806 Linux (s390x) U815807 v7.0 Platform Fix Pack 7.0.0.1 -------- -------------------- Windows U200301 AIX U821414 HP-UX (PA-RISC) U820765 HP-UX (Itanium) U821296 Solaris (SPARC) U820766 Solaris (x86-64) U820880 iSeries tbc_p700_0_0_1 Linux (x86) U821407 Linux (x86-64) U821295 Linux (zSeries) U821294 Linux (Power) U820881 The latest available maintenance can be obtained from 'Websphere MQ Recommended Fixes' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006037 If the maintenance level is not yet available, information on its planned availability can be found in 'Websphere MQ Planned Maintenance Release Dates' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006309 ---------------------------------------------------------------
