Subject [jira] [Created] (STORM-387) Memory leak in worker
Date Thu, 03 Jul 2014 22:02:36 GMT
Radim Kolar created STORM-387:

             Summary: Memory leak in worker
                 Key: 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:

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)
