APAR status

• Closed as program error.

Error description

• When an edition routing rule expression is modified, the
  processing of the modification causes a segmentation fault in
  the Intelligent Management enabled WebSphere plug-in. If an
  edition routing rule is created, but never modified, this
  problem will not occur.
  

Local fix

• Delete the entire edition routing rule, then recreate the rule
  with the new expression, rather than trying to modify the
  expression of an existing rule.

  ****************************************************************
  * PROBLEM DESCRIPTION: When a routing rule expression was      *
  *                      modified, the Intelligent Management    *
  *                      plug-in caused a segmentation fault.    *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  When a routing rule expression was modified, the memory for
  the original expression was freed twice. This caused a
  segmentation fault.
  

Problem conclusion

• The code was modified to eliminate the second free of the
  memory associated with the original expression.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 8.5.5.6.  Please refer to the Recommended Updates
