I've add verbose logging to the SSH deamon, and I notice something strange. 
I'am using a public key create a SSH connection, this is working correct. 
The connection is created successfully like the logs shows. As you can see 
the connection disconnections after a few seconds and a new connection is 
started. This repeats itself for almost an hour!!! This is probaly is 
creating a fork limit...

Do you know what could be wrong?
