Hi all, I'm using jboss cache 3.0.2 and have a cache configured with MVCC. The cache is being used by hibernate as a second level cache, in a 2 nodes cluster using INVALIDATION_SYNC. I have also configured the lockAcquisitionTimeout to 15000. The thing is I see exceptions like this: | [exec] 17:50:17,890 INFO [STDOUT] Caused by: org.jboss.cache.lock.TimeoutException: Unable to acquire lock on Fqn [/persistence.unit:unitName=SPECjAppServer.ear/corp.jar#corp-persistence/org/spec/jappserver/corp/customerinventoryent/ejb/CCustomerInventory/ENTITY/org.spec.jappserver.corp.customerinventoryent.ejb.CCustomerInventory#394737] after [0] milliseconds for requestor [Thread[Incoming-11,138.100.12.127:60763,10,Thread Pools]]! Lock held by [GlobalTransaction:<138.100.12.127:60763>:18482] | [exec] 17:50:17,891 INFO [STDOUT] at org.jboss.cache.mvcc.MVCCNodeHelper.acquireLock(MVCCNodeHelper.java:170) where I can read the cache is unable to get a lock after 0 milliseconds. Is there any other parameter that takes care of the timeoutexception, rather than lockAcquisitionTimeout? Thanks a lot !!
