deepankar created HBASE-15525: --------------------------------- Summary: Fix OutOfMemory that could occur when using BoundedByteBufferPool during RPC bursts Key: HBASE-15525 URL: https://issues.apache.org/jira/browse/HBASE-15525 Project: HBase Issue Type: Bug Components: IPC/RPC Reporter: deepankar
After HBASE-13819 the system some times run out of direct memory whenever there is some network congestion or some client side issues. This was because of pending RPCs in the RPCServer$Connection.responseQueue and since all the responses in this queue hold a buffer for cellblock from BoundedByteBufferPool this could takeup a lot of memory if the BoundedByteBufferPool's moving average settles down towards a higher value See the discussion here https://issues.apache.org/jira/browse/HBASE-13819?focusedCommentId=15207822&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15207822 -- This message was sent by Atlassian JIRA (v6.3.4#6332)
