APAR status

• Closed as program error.

Error description

• Its observed that an EGL generated CICS Web Service abends in
  the W-module with the following error:
  AT MAXIMUM NUMBER OF HEAPS
  CEE3204S The system detected a protection exception (System
  Completion Code=0C4C)
  From compile unit RSATAW at entry point RSATAW at compile unit
  offset +00066E0A at entry offset +00066E0A at address 1EF8865A.
  
  Development have confirmed this as a defect as it occurs due to
  the large amount of array definitions within the web service
  which the garbage collection cannot handle, so eventually the
  aforementioned abend is thrown.

Problem summary

• ****************************************************************
  * USERS AFFECTED:                                              *
  * CICS Web service users that have wsdl files that describe    *
  * numerous dynamic arrays                                      *
  ****************************************************************
  * PROBLEM DESCRIPTION:                                         *
  * The web service wrapper program that accepts the incoming    *
  * web service variables was not giving garbage collection a    *
  * chance to collect unused memory. If a web service request    *
  * came in, that had a reasonable number of dynamic arrays, the *
  * creation of those arrays, if large enough would cause the    *
  * heap memory manager to intentionally abend, as it thinks the *
  * program is faulty and in a loop.                             *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  

Problem conclusion

• The web service wrapper now permits garbage collection to run
  while it is collecting the incoming data.
