PM15043: MEMORY LEAK WHEN USING MULTI THREADED / MULTIPLE XML INPUT / MULTIPLE MAPS WITH WTX API

APAR status

• Closed as program error.

Error description

• There is a memory leak issue when calling multiple maps (each
  with a different transformation structure) under the WTX API.
  
  This has been discovered using different execution methods under
  WebSphere Application Server.  One type of map is being called
  when a file is dropped into a directory.  The other is
  called when a message arrives on a queue.
  
  Only when both maps are deployed can the leak be seen.
  

Local fix

• WTXCQ - WTX00033789
  PB / PB
  Circumvention: None
  

Problem summary

• Users Affected:
  WebSphere Transformation Extender users that are processing XML
  files via the WTX native XML handler.
  
  Problem Description:
  The processing of native XML schemas results in a significant
  memory leak.
  
  Platforms Affected:
  All
  

Problem conclusion

• The WTX XML parser was not freeing all the memory associated
  with processing a native XML schema.  This problem became
  apparent when running in a multi-threaded environment and using
  different types of XML files.
