I posted a similiar problem on Sunday but didn't get any responses.  I 
turned off DNS in the sshd_config file and the sshd time out problem went 
away for me as well.   Actually I had to turn off dns lookup up for apache 
and proftpd as well because those services were running extremely slow or 
not responding. 

If you've not made any modifications to your system, why would this happen?
