             Summary: Trouble starting Infinispan using a Cassandra cache store.
                 Key: ISPN-2068
                 URL: https://issues.jboss.org/browse/ISPN-2068
             Project: Infinispan
          Issue Type: Bug
          Components: Loaders and Stores
    Affects Versions: 5.1.4.FINAL
         Environment: Ubuntu server 10.04, OpenJDK 1.6.0_20
            Reporter: Giovanni Mels
            Assignee: Manik Surtani


I am using Infinispan on top of a Cassandra cache store. Whenever I start an Infinispan cluster node, and Cassandra contains data from a previous run, the application immediatly allocates all available memory (1GB) and after a few minutes I get OutOfMemory exceptions in org.infinispan.loaders.cassandra.CassandraCacheStore.purgeInternal.

If I purge Cassandra manually (TRUNCATE InfinispanEntries; TRUNCATE InfinispanExpiration;) and restart the application, everything works again.

Note that there were only around 10000 entries stored in Cassandra (around 150 MB spread over 2 nodes). 

Infinispan loaders configuration:

<loaders passivation="false" preload="false" shared="true">
     <loader class="org.infinispan.loaders.cassandra.CassandraCacheStore" fetchPersistentState="false" ignoreModifications="false" purgeOnStartup="false">
          <properties>
               <!--  property name="autoCreateKeyspace" value="true"/ -->
               <property name="host" value="localhost" />
               <property name="keySpace" value="Infinispan" />
               <property name="entryColumnFamily" value="InfinispanEntries" />
               <property name="expirationColumnFamily" value="InfinispanExpiration" />
               <property name="sharedKeyspace" value="false" />
               <property name="readConsistencyLevel" value="ONE" />
               <property name="writeConsistencyLevel" value="ONE" />
               <property name="configurationPropertiesFile" value="cassandrapool.properties" />
               <property name="keyMapper" value="org.infinispan.loaders.keymappers.DefaultTwoWayKey2StringMapper" />
          </properties>
     </loader>
</loaders>
