We have a jboss cluster with a Hibernate 2nd level cache via JBossCache. I'm receiving a lot of the following type of error and I'm unsure how to approach resolving it. It seems like the write lock times out instantly, but there aren't any existing locks:
[IdentityLock] write lock for ... could not be acquired after 0 ms. Locks: Read lock owners: [] Write lock owner: null (caller=Thread[http-0.0.0.0-8443-30], lock info: ([EMAIL PROTECTED])) JBoss version is 4.0.5 GA, JGroups & JBossCache are the versions that shipped with it. I have included our cache configuration file in case anything can be seen as obviously wrong therein: <?xml version="1.0" encoding="UTF-8"?> jboss:service=Naming jboss:service=TransactionManager Hibernate-${jboss.partition.name:Cluster} READ_COMMITTED REPL_ASYNC false false org.jboss.cache.BatchModeTransactionManagerLookup <UDP mcast_addr="${partition.udpgroup.hib3:228.1.2.3}" mcast_port="${partition.udpport.hib3:48866}" ucast_recv_buf_size="20000000" ucast_send_buf_size="640000" mcast_recv_buf_size="25000000" mcast_send_buf_size="640000" loopback="false" max_bundle_size="64000" max_bundle_timeout="30" use_incoming_packet_handler="true" use_outgoing_packet_handler="true" ip_ttl="${jgroups.mcast.ip_ttl:2}" enable_bundling="true"/> <PING timeout="2000" down_thread="false" num_initial_members="3"/> <MERGE2 max_interval="100000" down_thread="false" min_interval="20000"/> <FD_SOCK down_thread="false" /> <FD shun="true" down_thread="false" timeout="20000" max_tries="5"/> <VERIFY_SUSPECT timeout="1500" down_thread="false"/> <pbcast.NAKACK max_xmit_size="60000" use_mcast_xmit="false" gc_lag="50" retransmit_timeout="300,600,1200,2400,4800" down_thread="false" discard_delivered_msgs="true"/> <UNICAST timeout="300,600,1200,2400,3600" down_thread="false" /> <pbcast.STABLE stability_delay="1000" desired_avg_gossip="50000" down_thread="false" max_bytes="400000"/> <pbcast.GMS print_local_addr="true" join_timeout="3000" down_thread="false" join_retry_timeout="2000" shun="true"/> <FC max_credits="2000000" down_thread="false" min_threshold="0.10"/> <FRAG2 frag_size="60000" down_thread="false" up_thread="true"/> <pbcast.STATE_TRANSFER down_thread="false" up_thread="false"/> false 20000 20000 15000 false org.jboss.cache.buddyreplication.NextMemberBuddyLocator numBuddies = 1 ignoreColocatedBuddies = true default 2000 false true true View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4034207#4034207 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4034207 _______________________________________________ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user
