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.
