Duo Zhang updated HBASE-16165:
------------------------------
Priority: Minor (was: Major)
> Decrease RpcServer.callQueueSize before writeResponse causes OOM
> ----------------------------------------------------------------
>
> Key: HBASE-16165
> URL: https://issues.apache.org/jira/browse/HBASE-16165
> Project: HBase
> Issue Type: Bug
> Reporter: Duo Zhang
> Priority: Minor
>
> In RpcServer, we use {{callQueueSizeInBytes}} to avoid queuing too many calls
> which causes OOM. But in {{CallRunner.run}}, we decrease it before send the
> response back. And even after calling {{sendResponseIfReady}}, the call
> object could stay in our heap for a long time if we can not write out the
> response(That's why we need a Responder thread...). This makes it possible
> that the actual size of all call object in heap is larger than
> {{maxQueueSizeInBytes}} and causes OOM.
