Problem summary

• ****************************************************************
  * USERS AFFECTED:  All users of WebSphere Application Server   *
  *                  V6.1.0                                      *
  ****************************************************************
  * PROBLEM DESCRIPTION: OutOfMemory occurs in a large topology  *
  *                      when performing continuous application  *
  *                      deployments and/or resource creations.  *
  ****************************************************************
  * RECOMMENDATION:  Recycle the servers and try increasing the  *
  *                  size of the "-Xms -Xmx" java options.       *
  ****************************************************************
  An Out Of Memory condition occurs in large topologies when
  performing application deployments and/or resource creations. A
  javacore will show a lot of objects of type
  com.ibm.ws.sm.workspace.imp.RepositoryContextImpl.
  

Problem conclusion

• The code has been modified to improve the usage of memory by
  these objects.  With this change applied, the OutOfMemory
  condition did not reoccur in internal tests, however spikes in
  memory usage may still occur.
  
  APAR PK81327 is currently targeted for inclusion in
