Viraj Jasani created HBASE-26708:
------------------------------------
Summary: Netty Leak detected and eventually results in
OutOfDirectMemoryError
Key: HBASE-26708
URL: https://issues.apache.org/jira/browse/HBASE-26708
Project: HBase
Issue Type: Bug
Affects Versions: 2.4.6
Reporter: Viraj Jasani
Under constant data ingestion, using default Netty based RpcServer and
RpcClient implementation results in OutOfDirectMemoryError, supposedly caused
by leaks detected by Netty's LeakDetector.
