[infinispan-issues] [JBoss JIRA] (ISPN-2068) PurgeInternal operation in Cassandra cache store might lead to out of memory

PurgeInternal operation in Cassandra cache store might lead to out of memory ---------------------------------------------------------------------------- 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: Tristan Tarrant Fix For: 5.1.5.FINAL, 5.2.0.ALPHA2 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).
