Error description

Problem summary

• ****************************************************************
  USERS AFFECTED:
  All users of App Connect Enterprise V11 and V12 who configure
  their Integration Servers to load the sample AceSpanTraceExample
  user exit or implement a Transport Tracking user exit library
  based on the sample.
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  The Transport Tracking user exit allocates memory to a temporary
  buffer which is used to store the name of the message flow node
  that called out to the user exit library. The memory allocated
  to this temporary buffer was not being released.

  allocated to the temporary buffer that is used to store the
  message flow node name from which the transport tracking user
  exit was called from is now released.
