Error description
WebSphere MQ listener process fails to start with an AMQ9255 error reporting rrcE_LISTENER_ALREADY_RUNNING. The queue manager error logs will show a sequence of "AMQ5026: The Listener 'xxx' has started, followed shortly by "AMQ5027: The Listener 'xxx' has ended " messages. A trace of runmqlsr will show the AMQ9255 error as follows: 04:57:43.467556 1234.1 : ----}! socket rc=Unknown(11) 04:57:43.484936 1234.1 : ----{ rrxError 04:57:43.484996 1234.1 : RetCode = 20009255
Local fix
A graceful closure of the listener using endmqlsr(or similar command) prior to reboot or recycling of the queue manager would be a temporary workaround
Problem summary
**************************************************************** USERS AFFECTED: WMQ 7.1 users having multiple listeners and recycling them frequently may encounter this issue. Platforms affected: All Distributed (iSeries, all Unix and Windows) **************************************************************** PROBLEM SUMMARY: While starting a listener WMQ generally checks and tidy up the old socket files. But in some special cases where remnants of the previous listener socket files are sill active there could be problem where WMQ might think a listener is already running.
Problem conclusion
Code changes have been carried out to clean up the old socket files before starting a listener. --------------------------------------------------------------- The fix is targeted for delivery in the following: v7.1 Platform Fix Pack 7.1.0.4 -------- -------------------- Windows 7.1.0.4 AIX 7.1.0.4 HP-UX (Itanium) 7.1.0.4 Solaris (SPARC) 7.1.0.4 Solaris (x86-64) 7.1.0.4 iSeries 7.1.0.4 Linux (x86) 7.1.0.4 Linux (x86-64) 7.1.0.4 Linux (zSeries) 7.1.0.4 Linux (Power) 7.1.0.4 Version v7.5 -------- -------------------- Fix available in: 7.5.0.3 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 ---------------------------------------------------------------
