APAR status

• Closed as program error.

Error description

• MultipartRequest.java creates temp files in method
  processFile(). These temp files are not properly cleaned up when
   they are needed no longer. Therefore they can accumulate in the
   OS temp directory and cause performance issues over time.
  

Local fix

• manually delete OS temp file directory
  

Problem summary

• In the temp folder of the operating system the number of temp
  files are increasing over time, which causes performance issues
  with coaches.
  
  PROBLEM DETAILED DESCRIPTION:
  When processing HTTP requests coming from coaches the
  processing of the HTTP request results in temp files in the temp
  folder of the operating system, which are not cleaned up
  properly in call situations. So the number of temp files in the
  temp folder are increasing over time.
  

Problem conclusion

• With this interim fix all temp files that are created in the
  context of processing HTTP requests are cleaned up when the
  HTTP request is processed and the garbage collector is cleaning
  up the corresponding Java object instances.
