Michael, Thanks for the response. Below is the stack trace.
Note: Our environment is 64 bit and the Initial Pool size is set to 4GB and Max pool size is 12GB so it doesn't makes sense why it tries to allocate 24GB (even that is available as the total RAM is 64GB). This issue doesn't come with SOLR 1.4 ----------------------------------------- SEVERE: Error waiting for multi-thread deployment of directories to completehostConfig.deployWar=Deploying web application archive {0} java.util.concurrent.ExecutionException: java.lang.OutOfMemoryError: classblock allocation, 1535880 loaded, 1536K footprint, in check_alloc (src/jvm/model/classload/classalloc.c:215).
