PH54195: ABEND IN IMBCMPCLIENTHANDLERTHREAD() DESTRUCTOR DURING MQSILIST COMMANDS

APAR status

• Closed as program error.

Error description

• During a batch of mqsilist commands, an abend with the following
  traceback stack was generated:
  
  ImbDumpAndTerminate(int,const void*)
  ImbAbend::terminateProcessInternal(const void*,bool)
  ImbAbend::logSystemErrorAndTerminateProcessInternal(const ch
  ImbDeployManagerLocalCMPListener::ImbCMPClientHandlerThread::&#1
  26;I
  mbCMPClientHandlerThread()
  ImbDeployManagerLocalCMPListener::ImbCMPClientHandlerThread::ru
  n(ImbOsThread*)
  ImbThreadPoolThreadFunction::run(ImbOsThread*)
  ImbOsThread::threadRun()
  ImbOsThread::innerThreadBootStrapWrapper(void*)
  ImbOsThread::threadBootStrap(void*)
  threadBootStrapWrapper
  
  The following message is also logged to the joblog/syslog:
  
  BIP2228E (Msg 1/1) BROKER.agent 3391641527968071798
  Severe error: /build/jenkins/slot0/productbuild/WMB/export/mvs3
  90_oe_2/usr/include/ImbMutex.inl 135

  Abend file:/instpath/BROKER/common/errors/BROKER.agent.67109762
  .3391641527968071798.abend
  action: abort
  

Local fix

• Running the commands with the -v flag appears to workaround the
  issue.
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  All users of IBM Integration Bus v10 and v10.1 and App Connect
  Enterprise v11 and v12
  
  
  Platforms affected:
  MultiPlatform, z/OS
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  A pthread_mutex_destroy call might fail with errno EBUSY and a
  BIP2228E error, for example as below, may be logged to the
  system:
  
  +BIP2228E (Msg 1/1) BROKER.agent nnnnnnnnnnnnnnnnnnnnnn Severe
  error:
  /build/jenkins/slot0/productbuild/WMB/export/mvs390_oe_2/usr/inc
  lude/
  ImbMutex.inl 135 pthread_mutex_destroy
  Abend file:b/opt/local/lpp/mqsi/brokers/BROKER/common/errors/
  BROKER.agent.nnnnnn.nnnnnnnnnnnnnnnnnnnnnn.abend action: abort
  
  An example of a failing stack leading to the
  pthread_mutex_destroy failure, as observed in IIB  v10
  /10.1.0.1, occurs in the ImbDeployManagerLocalCMPListener as
  follows:
  
  ImbDumpAndTerminate(int,const void*)
  ImbAbend::terminateProcessInternal(const void*,bool)
  ImbAbend::logSystemErrorAndTerminateProcessInternal(const ch
  ImbDeployManagerLocalCMPListener::ImbCMPClientHandlerThread::&#1
  26;ImbCMPClientHandlerThread()
  ImbDeployManagerLocalCMPListener::ImbCMPClientHandlerThread::run
  (ImbOsThread*)
  

Problem conclusion

• The product has been modified so that the abend no longer
  occurs.
