Local fix

• N/A
  

Problem summary

• Users affected: All IWWCM users
  
  Detailed Problem Description:
  
  If PK67898 is installed on the syndicator server and a rebuild
  syndication is attempted for a library containing a large number
  of items, an Out of Memory error might be seen. A large
  StrongWorkspaceState object can be seen on the object heap.
  

Problem conclusion

• Problem Analysis:
  
  PK67898 introduced a new method in the logic that generates the
  list of items to be sent during syndication. This new method
  will retrieve a large number of items from the repository using
  the same workspace object. This can lead to increased heap
  usage.
  
  Failing Module: WCM - Web Content Management (General)
  
  Problem Solution:
  
  Added changes to clear all workspaces used by the syndication
  thread regularly.
  
  A fix for this problem is available for WCM 6.0.1.3 from Fix
