Local fix
Problem summary
**************************************************************** USERS AFFECTED: Users using lot of queues and/or dynamic queues. Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: This problem occurred because MQ did not properly initialize a file descriptor variable to -1. This caused MQ to close and reuse file descriptor value 0 and subsequently resulted in failure when the file descriptor 0 was again closed.
Problem conclusion
MQ has been modified to properly initialize the file descriptor variable with value -1. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v7.0 7.0.1.13 v7.1 7.1.0.6 v7.5 7.5.0.5 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 ---------------------------------------------------------------
