Error description
When initializing near-cache invalidation, a deadlock can occur. Because the deadlock never resolves itself, near-cache invalidation initialization does not complete.
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: WebSphere eXtreme Scale customers who run * * with near-cache invalidation. * **************************************************************** * PROBLEM DESCRIPTION: Deadlocks might occur during * * near-cache invalidation * * initialization. * **************************************************************** * RECOMMENDATION: * **************************************************************** During near-cache invalidation initialization, a near-cache invalidation listener must be registered with the server. If the registration for the listener occurred at the same time that existing listeners were being updated, then a deadlock scenario might occur. Because the deadlock never resolves itself, near-cache invalidation initialization never completes.
Problem conclusion
The lock mode sequence was reorganized. Now, when you add a near-cache invalidation listener, deadlocks no longer occur.
Temporary fix
