Rohit Joshi commented on HBASE-9939:
------------------------------------

Lars,
Thanks for looking into this.  
To release the client threads running under weblogic container,  I used following  configuration
and it is able to release threads under 100 seconds (zookeeper timeout + retry + HBase timeout
+ retry). But I was able to reproduce threads lockout twice and it did not release for long
time.

hbase.rpc.timeout=3000
hbase.client.operation.timeout=3000
hbase.client.pause=100
hbase.client.retries.number=2
zookeeper.session.timeout=10000
zookeeper.recovery.retry.intervalmill=100
zookeeper.recovery.retry=1

> Under load when I disabled network interface, all HBase threads were locked out.  I was
expecting these threads to be released based on client.operation.timeout and rpc,timeout.
> Here is a link for  thread dump.
