    Trouble starting Infinispan using a Cassandra cache store.

    Giovanni Mels Newbie

      Hi,

       

      I am currently evaluating 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).

       

      Have I found a bug or am I missing something? I am using Infinispan 5.1.4 and Cassandra 1.0.10.

       

      Thanks.

       

      My 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>
      

       

       

      The stack trace:
