  This can happen because some native ACE threads are not detached
  from the JVM when they are shutdown.
  

Local fix

• NIL
  

Problem summary

• ****************************************************************
  
  USERS AFFECTED:
  All users of IBM App Connect Enterprise using third party
  monitoring tools or User Exits.
  
  
  Platforms affected:
  AIX, LinuxZ64, LinuxX64, LinuxPPCLE64, WinX64
  
  ****************************************************************
  
  PROBLEM DESCRIPTION:
  An Integration Server configured with User Exits or third-party
  monitoring tools may abend, with the generated abend file
  displaying the following call stack :
  
  #6 0x7f2d165835b0 in ??
  from /lib64/libc.so.6
  #7 0x7f2d12ecfc24 in pthread_getcpuclockid
  from /lib64/libpthread.so.0
  #8 0x7f2d101040fd in
  omrthread_get_cpu_time_ex from
  /opt/ibm/ace-12.0.12.12/common/jdk/jre/lib/amd64/compressedrefs/
  
  libj9thr29.so
  #9 0x7f2d10104267 in omrthread_get_cpu_time from
  /opt/ibm/ace-12.0.12.12/common/jdk/jre/lib/amd64/compressedrefs/
  
  libj9thr29.so
  #10 0x7f2cf84ccb05 in ?? from
  /opt/ibm/ace-12.0.12.12/common/jdk/jre/lib/amd64/compressedrefs/
  
  libj9jvmti29.so
  
  This can happen because some native ACE threads
  are not detached from the JVM when they are shutdown.
  

Problem conclusion

• Integration Servers configured with User Exits or third-party
  monitoring tools no longer abends.
