Anoop Sam John commented on HBASE-15525: ---------------------------------------- I made it critical because it make it very difficult for the user to work out what should be the max off heap size > OutOfMemory 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 > Assignee: Anoop Sam John > Priority: Critical > > 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 > [HBASE-13819-comment|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)
