Error description
While running dmqmqcfg, if it requests the security policies, a memory corruption occurs that leads to the abnormal termination of the command server process (amqpcsea) and the subsequent errors reported by the other queue manager processes. The FDCs generated as a result are similar to the following: Probe Id :- XY398006 Component :- xcsFreeMemBlock SCCS Info :- /build/slot1/p800_P/src/lib/cs/amqxstma.c, Program Name :- amqpcsea Probe Description :- AMQ6109: An internal WebSphere MQ error has occurred.

Problem summary
**************************************************************** USERS AFFECTED: Users running MQ applications which inquires policies set on a queue using PCF or MQSC commands, and have more than 1024 security policies defined. This problem can also manifest as unexpected large return code values when running dspmqspl to display security policies when the queue manager has more than 1024 security policies defined. Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: A buffer used internally within the queue manager when responding to a policy inquire request was not sized appropriately to handle scenarios when a large number of policies (more than 1024) were defined to the queue manager. This could lead to memory areas within the queue manager processes being incorrectly overwritten.
Problem conclusion
The problem has been addressed by correcting the size calculation used to allocate the buffer when the queue manager responds to an inquire request for security policies. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v8.0 8.0.0.6 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 ---------------------------------------------------------------
