Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server using dynamic cache with multiple * * cache instances. * **************************************************************** * PROBLEM DESCRIPTION: The application server may fail to * * start when an error occurs creating * * cache instances. * **************************************************************** * RECOMMENDATION: * **************************************************************** The dynacache service maintains a collection of cache instance configurations. Access to the collection is not thread safe and could result in a ConcurrentModificationException if multiple threads are creating cache instances simultaneously.
Problem conclusion
The collection that houses the cache instance configurations has been changed to a thread safe collection. The fix for this APAR is currently targeted for inclusion in fix packs 7.0.0.33, 8.0.0.9 and 8.5.5.3.
