Regionserver Deadlock

                 Key: HBASE-4101
                 URL: https://issues.apache.org/jira/browse/HBASE-4101
             Project: HBase
          Issue Type: Bug
          Components: regionserver
    Affects Versions: 0.90.3
         Environment: CentOS 5.5, CDH3 u0 Hadoop, HBase 0.90.3
            Reporter: Matt Davies
         Attachments: jstack.txt

We periodically see a situation where the regionserver process exists in the process list,
zookeeper thread sends the keepalive so the master won't remove it from the active list, yet
the regionserver will not serve data.

Hadoop(cdh3u0), HBase 0.90.3 (Apache version), under load from an internal testing tool.

Attached is the full JStack
