[jira] [Updated] (STORM-339) Severe memory leak to OOM when ackers
disabled
[ https://issues.apache.org/jira/browse/STORM-339?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Michael Noll updated STORM-339:
-------------------------------
Summary: Severe memory leak to OOM when ackers disabled (was: serere memory leak to OOM)
> Severe memory leak to OOM when ackers disabled
> ----------------------------------------------
>
> Key: STORM-339
> URL: https://issues.apache.org/jira/browse/STORM-339
> Project: Apache Storm (Incubating)
> Issue Type: Bug
> Affects Versions: 0.9.2-incubating
> Reporter: Jiahong Li
> Priority: Critical
>
> Without any ackers enabled, fast component will continuously leak memory and causing OOM problems when target component is slow. The OOM problem can be reproduced by running this fast-slow-topology
> https://github.com/Gvain/storm-perf-test/tree/fast-slow-topology
> with command:
> storm jar storm_perf_test-1.0.0-SNAPSHOT-jar-with-dependencies.jar com.yahoo.storm.perftest.Main --spout 1 --bolt 1 --workers 2 --testTime 600 --messageSize 6400
> And the worker childopts with -Xms2g -Xmx2g -Xmn512m ...
> At the same time, the executed count of target component is far behind from the emitted count of source component.
> I guess it could be that netty client is buffering too much messages in its mesage_queue as target component sends back OK/Failure Response too slowly.
