Error description
The error "AMQ6150: IBM MQ semaphore is busy" in the error logs states a timeout of 0 minutes: ----- amqxfdcx.c : 885 ----- 01/04/2021 11:45:26 AM - Process(31411.125) User(mqm) Program(amqrmppa) Host(www.example.com) Installation(Installation1) VRMF(9.0.0.9) AMQ6150: IBM MQ semaphore is busy. EXPLANATION: IBM MQ was unable to acquire a semaphore within the normal timeout period of 0 minutes. The "of 0 minutes" at the end of the sentence does not provide any value to debugging the actual problem of the semaphore being locked by another process.
Local fix
Problem summary
**************************************************************** USERS AFFECTED: All users receiving the AMQ6150 error message Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: Due to the asynchronous reporting of errors within performance-sensitive sections of MQ code, the length of the timeout incurred is not accessible when the AMQ6150 message is generated. As such, the timeout value is treated as zero, and should not have been included in the message text.
Problem conclusion
The error reporting code has been updated to prevent the inclusion of the misleading "0 minutes" statement. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v9.0 LTS 9.0.0.12 v9.1 LTS 9.1.0.8 v9.2 LTS 9.2.0.3 v9.x CD 9.2.3 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 ---------------------------------------------------------------
