Hi I am using pojo cache. When I try to write to the data base I get a exception. It happens while there is no one else writing or reading to the cache and it happens consistently only on 64b machines. When I do it on 32b machine it never happens. The exception is as follows: 2008-01-23 17:32:57,560 ERROR [com.bevents.engine.engineserver.server.EngineServerImpl] org.jboss.cache.lock.TimeoutException: failure acquiring lock: fqn=/EVENTS/20/d1-0;d2-0;d3-0;d4-0;d5-1;d7-2;d10-0;d11-3;d12-2;d13-1, caller=Thread[RMI TCP Connection(37)-192.168.10.201,5,RMI Runtime], lock=write owner=GlobalTransaction::81 (org.jboss.cache.lock.LockStrategyReadCommitted@4d402172) org.jboss.cache.lock.TimeoutException: failure acquiring lock: fqn=/EVENTS/20/d1-0;d2-0;d3-0;d4-0;d5-1;d7-2;d10-0;d11-3;d12-2;d13-1, caller=Thread[RMI TCP Connection(37)-192.168.10.201,5,RMI Runtime], lock=write owner=GlobalTransaction::81 (org.jboss.cache.lock.LockStrategyReadCommitted@4d402172) at org.jboss.cache.lock.IdentityLock.acquire(IdentityLock.java:528) at org.jboss.cache.interceptors.PessimisticLockInterceptor$LockManager.acquire(PessimisticLockInterceptor.java:579) at org.jboss.cache.interceptors.PessimisticLockInterceptor.acquireNodeLock(PessimisticLockInterceptor.java:393) at org.jboss.cache.interceptors.PessimisticLockInterceptor.lock(PessimisticLockInterceptor.java:329) at org.jboss.cache.interceptors.PessimisticLockInterceptor.invoke(PessimisticLockInterceptor.java:187) at org.jboss.cache.interceptors.Interceptor.invoke(Interceptor.java:76) at org.jboss.cache.interceptors.NotificationInterceptor.invoke(NotificationInterceptor.java:32) at org.jboss.cache.interceptors.Interceptor.invoke(Interceptor.java:76) at org.jboss.cache.interceptors.TxInterceptor.handleNonTxMethod(TxInterceptor.java:298) at org.jboss.cache.interceptors.TxInterceptor.invoke(TxInterceptor.java:131) at org.jboss.cache.interceptors.Interceptor.invoke(Interceptor.java:76) at org.jboss.cache.interceptors.CacheMgmtInterceptor.invoke(CacheMgmtInterceptor.java:81) at org.jboss.cache.interceptors.Interceptor.invoke(Interceptor.java:76) at org.jboss.cache.interceptors.InvocationContextInterceptor.invoke(InvocationContextInterceptor.java:62) at org.jboss.cache.CacheImpl.invokeMethod(CacheImpl.java:3939) at org.jboss.cache.CacheImpl.get(CacheImpl.java:1441) at org.jboss.cache.CacheImpl.get(CacheImpl.java:1415) Does anyone have any idea what can be the cause for this excpetion? hanks in advance, Anat View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4123040#...
