Subject [jira] [Created] (HBASE-5141) Memory leak in MonitoredRPCHandlerImpl

Memory leak in MonitoredRPCHandlerImpl

                 Key: HBASE-5141
                 URL: https://issues.apache.org/jira/browse/HBASE-5141
             Project: HBase
          Issue Type: Bug
    Affects Versions: 0.92.0
            Reporter: Jean-Daniel Cryans
            Priority: Blocker
             Fix For: 0.92.0, 0.94.0

I got a pretty reliable way of OOME'ing my region servers. Using a big payload (64MB in my
case), a default heap and default number of handlers, it's not too long that all the MonitoredRPCHandlerImpl
hold on a 64MB reference and once a compaction kicks in it kills everything.

The issue is that even after the RPC call is done, the packet still lives in MonitoredRPCHandlerImpl.

Will attach a screen shot of jprofiler's analysis in a moment.

This is a blocker for 0.92.0, anyone using a high number of handlers and bigish values will
kill themselves.
