Jboss Cache DataContainer should allow printDetails write to a file to save JVM memory cost ------------------------------------------------------------------------------------------- Key: JBCACHE-1637 URL: https://issues.jboss.org/browse/JBCACHE-1637 Project: JBoss Cache Issue Type: Feature Request Security Level: Public(Everyone can see) Components: JMX Affects Versions: 3.2.5.GA, 3.3.0.GA Reporter: Nghi Nguyen Van Assignee: Manik Surtani * Our application environment have Xmx=3gb. While it is running the used memory is around 90% of the JVM capacity (~2.7GB) including >500MB cached content by Jboss cache. If I want to dump the jboss cached content out of the JVM the application then got OutOfMemoryError. The problem come from the way JbossCache use JVM memory to response back to JMX client, it nearly double JbossCache used memory: 2.7gb + 500Mb=3.3gb > JVM capacity. I think that JBossCache should improve by: # response content back to JMX client continuously # provide option to write content to an output file
