Problem summary

****************************************************************
* USERS AFFECTED:  All users of IBM WebSphere Application      *
*                  Server V6.0.1 using dynacache for object    *
*                  caching.                                    *
****************************************************************
* PROBLEM DESCRIPTION: A stack overflow exception occurs       *
*                      when the object cache is full and       *
*                      objects are being evicted.              *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
Cache entries are removed from the object cache using a least
recently used (LRU) algorithm when the object cache has reached
the maximum cache size.  If removing an object from the cache
fails an infinite recursive loop can occur trying to remove
the object.

Problem conclusion

The LRU algorthim has been modified to recognize that a remove
has failed and the next LRU object is then removed.

APAR PM06078 is currently targeted for inclusion in Service
Level (Fix Pack) 6.0.2.41 of WebSphere Application Server
V6.0.1.
