Problem summary

• ****************************************************************
  * USERS AFFECTED: All ITMS/ENGINE users.                       *
  ****************************************************************
  * PROBLEM DESCRIPTION: PTHREAD_MUTEX_TRYLOCK FAILURES FILL UP  *
  *                      RAS1 LOGS.                              *
  ****************************************************************
  * RECOMMENDATION: Apply the PTF.                               *
  ****************************************************************
  The pthread_mutex_trylock function prints a RAS1 message to
  the log with KBB_RAS1=ERROR configured and when the call
  returns EBUSY.  This is too much detail for 'ERROR' level
  tracing and should only be printed for KBB_RAS1=STATE or
  KLX_DEBUG=D.
  

Problem conclusion

• The code was changed to print non-zero completion ERRNO
  values when RAS1 tracing is set to State or Detail trace
  classes.
