[jboss-user] [JBossCache] - lock acquisition failed - pessimistic locking - read_uncommi

Hi i had posted a locking issue previously http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4117973#... this was my mistake, there was a synchronization problem while cache creation and there were 2 instances running ! now i have fixed and upgraded to jboss cache 2.0.0. yesterday i got the following lock issue - 10:52:55,679 INFO [WorkerThread#3[192.168.20.157:54241]] Exception while trying to write into cache : failure acquiring lock: fqn=/Indicatives/SAIL04035, caller=GlobalTransaction:<192.168.20.134:51000>:838, lock=write owner=GlobalTransaction:<192.168.20.134:51000>:837 (org.jboss.cache.lock.LockStrategyReadUncommitted@edeb72) 10:52:55,679 INFO [WorkerThread#4[192.168.20.157:54246]] Exception while trying to write into cache : failure acquiring lock: fqn=/Indicatives/SAIL04034, caller=GlobalTransaction:<192.168.20.134:51000>:837, lock=write owner=GlobalTransaction:<192.168.20.134:51000>:838 (org.jboss.cache.lock.LockStrategyReadUncommitted@1011edf) i can see that both threads have accessed at the same time. this is the drawback of pessimistic locking and i should move to optimistic locking ?
