Dear all,

When working with large amount of user, we have an error:

ERROR [main] 2010-02-01 17:12:37,354 CassandraDaemon.java (line 71) Fatal exception in thread Thread[main,5,main]

I see a lot of CLOSE_WAIT TCP connection.
And when I use Java Monitor and Management Console, I see the thread increase very fast.

Could you help me?
Thank a lot for support.
