IT18222: EXCESSIVE MEMORY USE BY MAPPING NODE

APAR status

• Closed as program error.

Error description

• Mapping node will use excessive memory when the message is
  processed continuously by the node without exiting the flow.
  
  This memory is taken by various parser objects. Setting the
  environment variable MQSI_FREE_MASTER_PARSERS will free the
  memory when the message exits the flow, but not while the
  message is being processed.
  

Local fix

• n/a
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  All users of IBM Integration Bus and the Mapping node.
  
  
  Platforms affected:
  z/OS, MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  The Mapping node will use excessive memory when a preceding node
  is propagating messages in a loop to be transformed by the
  mapping
  node without exiting the flow.
  
  This memory is taken by various parser objects associated with
  message
  headers being held by the Mapping node.
  
  Setting the environment variable MQSI_FREE_MASTER_PARSERS will
  free the
  memory when the flow exits the loop and completes, however
  memory will
  continue to grow while the flow is looping.
  
  There are a number of resource name changes between WebSphere
  Message Broker and IBM Integration Bus Version 9.0.  For details

  tools.mft.doc/bb23814_.htm
  

Problem conclusion

• The Mapping node no longer uses excessive memory.
