I got the dump of the problematic rs from web ui:
http://pastebin.com/4hfhkDUw
output of "top -H -p <PID>": http://pastebin.com/LtzkScYY
I also got the output of jstack but I believe it's already in the dump
so I do not paste it again. This time the hang lasted about 20 minutes.

Hi Rural,
Thats interesting. Since you are passing
hbase.zookeeper.property.maxClientCnxns does it means that ZK is managed by
HBase? If you experience the issue again, can you try to obtain a jstack
(as the user that started the hbase process or try from the RS UI if
responsive rs:port/dump) as Ted suggested? the output of "top -H -p <PID>"
might be useful too where <PID> is the pid of the RS. If you have some
metrics monitoring it would be interesting to see how callQueueLength and
the blocked threads change over time.
cheers,
esteban.
