Running out of memory using Infinispan after adding a small number of entities ------------------------------------------------------------------------------ Key: ISPN-868 URL: https://issues.jboss.org/browse/ISPN-868 Project: Infinispan Issue Type: Bug Affects Versions: 4.2.0.Final Environment: JBossJTA 4.14.0/Hibernate 3.6.0.Final/Spring 3.0.5 Reporter: Tom Waterhouse Assignee: Galder Zamarreño Fix For: 4.2.1.Final Attachments: ISPN-868-1.zip, ISPN-868.zip, ispn686-error-galder.txt, jconsole-mbeans.JPG, jconsole-memory-view.JPG, Memory leak.jpg, test-progress.JPG, With proper fix.jpg While running a load test data builder for our application we ran out of memory very quickly. A simple test case (attached) was created to duplicate the issue. We found running the simple test case illustrates that Infinispan uses a large amount of heap space. As a reference the same test was run using EHCache 2.2. Memory usage was much lower; we never ran out of heap space. Note that EHCache was used as a reference only, our goal is to go to production with Infinispan.
