Problem summary
**************************************************************** USERS AFFECTED: Users of distributed publish/subscribe. Platforms affected: All Distributed (iSeries, all Unix and Windows) **************************************************************** PROBLEM SUMMARY: This was caused by the MQRC_Q_MGR_QUIESCING return code from an MQOPEN call being ignored by the distributed publish/subscribe proxy sub task. No checks were made on the queue object handle when MQPUT was called, causing the amqzlaa0 agent process to SIGSEGV.
Problem conclusion
If MQRC_Q_MGR_QUIESCING is returned from an MQOPEN call it will prevent the MQPUT call from being issued. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: v7.0 Platform Fix Pack 7.0.1.8 -------- -------------------- Windows U200335 AIX U845856 HP-UX (PA-RISC) U847965 HP-UX (Itanium) U847970 Solaris (SPARC) U847966 Solaris (x86-64) U847972 iSeries 7.0.1.8 Linux (x86) U847967 Linux (x86-64) U847971 Linux (zSeries) U847968 Linux (Power) U847969 v7.1 Platform Fix Pack 7.1.0.1 -------- -------------------- Windows 7.1.0.1 AIX 7.1.0.1 HP-UX (Itanium) 7.1.0.1 Solaris (SPARC) 7.1.0.1 Solaris (x86-64) 7.1.0.1 iSeries 7.1.0.1 Linux (x86) 7.1.0.1 Linux (x86-64) 7.1.0.1 Linux (zSeries) 7.1.0.1 Linux (Power) 7.1.0.1 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 ---------------------------------------------------------------
