[jboss-user] [JBoss Cache: Core Edition] - Re: Possible deadlock with JBoss Cache? - Timeout exceptions

Additional Note:

Though we do configure for clustering, there is only one node in this case. See more configuration details below.  


Eviction configuration. 

    <eviction wakeUpInterval="3000">

  |     	<jgroupsConfig configFile="jgroups-config.xml"/>
  |     </clustering> 
  |     


The atomikos transaction manager is injected using the DummyTransactionManager. See configuration below. 

<!--
  |     Used to register a transaction manager and participate in ongoing transactions. There is no 
  |     JNDI present, since we are out of the container. Dummy lookup. 
  |     The transaction manager is injected programatically.
  |     -->
  |     <transaction transactionManagerLookupClass="org.jboss.cache.transaction.DummyTransactionManagerLookup"
  |             syncRollbackPhase="true"
  |             syncCommitPhase="true"/>
