Error description
An access violation occurs in the command server process leading to it terminating abnormally. An FDC with probe ID XC130031 is generated. The FDC originates in the amqpcsea process and has the following stack: MQM Function Stack pcmMain pcmProcessMessage pcmSendNonDataReplyMsg xcsFFST An application was performing system administration on the queue manager by putting PCF messages to the SYSTEM.ADMIN.COMMAND.QUEUE when the access violation occurred.
Local fix
Set the queue manager attribute Publish/Subscribe to Enabled. With Publish/Subscribe enabled, the application just returns the error but the command server is not stopped and there is dead-letter queue message.
Problem summary
**************************************************************** USERS AFFECTED: Any users of WebSphere MQ who use applications that put PCF messages to the SYSTEM.ADMIN.COMMAND.QUEUE. Platforms affected: All Distributed (iSeries, all Unix and Windows) **************************************************************** PROBLEM SUMMARY: The problem was caused by the fact that the MQ command server was unable to successfully put a message to a reply queue whilst processing a PCF request. A logic error within the code path to deal with this situation resulted in a storage overwrite which caused the command server to crash.
Problem conclusion
WebSphere MQ was modified to ensure that the code path dealing with rerouting a PCF reply message to a different queue as the result of failing to write it to the reply queue did not cause the command server to crash. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: v7.0 Platform Fix Pack 7.0.1.1 -------- -------------------- Windows U200310 AIX U827232 HP-UX (PA-RISC) U826485 HP-UX (Itanium) U826884 Solaris (SPARC) U827125 Solaris (x86-64) U827374 iSeries tbc_p700_0_1_1 Linux (x86) U826321 Linux (x86-64) U827231 Linux (zSeries) U827105 Linux (Power) U826779 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 ---------------------------------------------------------------
