Re: 3.11.2 memory leak

At this point I'd wait for 3.11.3. If you can't, you can get away with backporting a few repair fixes or just doing sub range repairs on 3.11.2

FWIW, when talking about https://issues.apache.org/jira/browse/CASSANDRA-13929, there is a patch available since March without getting further attention.

There have been a few people who have reported it, but nobody (yet) has offered a patch to fix it. It would be good to have a reliable way to repro, and/or an analysis of a heap dump demonstrating the problem (what's actually retained at the time you're OOM'ing).

Hi All,


I recently upgraded my non prod cluster from 3.10 to 3.11.2.

It was working fine for a 1.5 weeks then suddenly nodetool info startee reporting 80% and more memory consumption.

Intially it was 16gb configured, then i bumped to 20gb and rebooted all 4 nodes of cluster-single DC.

Now after 8 days i again see 80% + usage and its 16gb and above ..which we never saw before .

Seems like memory leak bug?

Does anyone has any idea ? Our 3.11.2 release rollout has been halted because of this.

If not 3.11.2 whats the next best stable release we have now?
