    Infinispan cache heap space problem

    vedanth k r Newbie

      We have an application which consists of JPA entities, EJB 3 stateless beans and infinispan   as second level cache.

       

      Jboss version : EAP-6.0.1

      OS  : Cent OS-6.2(Final) 64 bit

      Java : OpenJDK version "1.6.0_24"

       

          Min and Max memory supplied is -Xms1303m -Xmx4096m. On start of jboss initial heap size

          without any deployments is 264Mb

       

       

          CASE 1:

          When we try to deploy the application all the infinispan Mbeans gets registered and the total

          heap space occupied is around 2Gb with 350 cache entries(without any data).

          Then when we undeploy the application all the infinispan Mbeans gets unregistered, but the

          heap size still remains 1.8Gb.

       

       

          CASE 2:

          When we try to deploy the application with infinispan(second level cache)disabled, the

          heap space occupied is around 900Mb.

          Then when we undeploy the application the heap size goes back to the initial stage i.e,

          200Mb

       

       

          We wanted to know why the heap is not getting cleared with infinispan second level cache.

          Attachment contains the persistence.xml which is used to cache the entities,

          standalone-full.xml(Jboss is started using standalone-full.xml), server log.

          We are going with default inifinispan configuration provided as part of EAP-6.0.1.

       

       

          Am not able to attach heap dump as the size is almost 3.5Gb
