write lock timeout, but no transactions and async replicatio

Hi, I got an error:

javax.ejb.EJBException: nested exception is: java.lang.RuntimeException: getCachedProfileTO -write lock for /Profile could not be acquired after 15000 ms. Locks: Read lock owners: [Thread[233238|33238|inventory,5,Thread Group for Queue: 'weblogic.kernel.Default'], Thread[842112|42112|inventory,5,Thread Group for Queue: 'weblogic.kernel.Default']]
Write lock owner: null
(caller=Thread[951787|51787|inventory,5,Thread Group for Queue: 'weblogic.kernel.Default'], lock info: read owners=[Thread[233238|33238|inventory,5,Thread Group for Queue: 'weblogic.kernel.Default']] (activeReaders=1, activeWriter=null, waitingReaders=0, waitingWriters=0, waitingUpgrader=0))

I don't know how it's possible because cache isn't associated with transaction manager and replication is asynchronious. Could you show me the scenario in which such error will occur?

Multiple threads reading from and writing to the same cache. You don't necessarily need a TM for this - you can tell by looking at the lock owners - they're Threads, not GlobalTransaction instances.

I've found the problem. Thanks a lot!
