Dear all,

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

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

java.lang.OutOfMemoryError: unable to create new native thread

        at org.apache.cassandra.service.CassandraDaemon.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.

Best regards,
