             Summary: Memory leak in worker
                 Key: STORM-387
                 URL: https://issues.apache.org/jira/browse/STORM-387
             Project: Apache Storm (Incubating)
          Issue Type: Bug
    Affects Versions: 0.9.2-incubating
         Environment: FreeBSD 10/i386
            Reporter: Radim Kolar


There is memory leak in worker. I can reproduce it every time with following code: 

https://github.com/hsn10/stormtest

worker running bolt 'rtt' only leaks memory. Deploy topology and leave it about 15 minutes running until worker is killed by supervisor due to heartbeat timeout. It timeouts because its busy running gc all the time as you can see in jconsole.

I was able to do memory dump, but due to its size jhat tool was not able to load it in reasonable time (i killed it after 30 minutes)
