     [ https://issues.apache.org/jira/browse/KAFKA-1043?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jun Rao updated KAFKA-1043:
---------------------------

    Fix Version/s:     (was: 0.8)

moving this to 0.8.1 since the issue happens rarely.

> Since in SocketServer the processor who takes any request is also responsible for writing the response for that request, we make each processor owning its own response queue. If a FetchRequest takes irregularly long time to write the channel buffer it would block all other responses in the queue.
