             Summary: 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)
    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
