Hi Bill.

I got similar problem some weeks ago. With similar I mean so much more time 
when triying to log into a server trough ssh. Neither the same distro nor DNS 
problem.

After changing thousands of things of sshd_config and stuff, I was still on 
troubles. Finally, I realized that real problem was the load of that machine, 
it was at least 10 or 15, so I kill the process (apache one) and everything 
went normal.

I supposse you to know what your average load is, but, these are my 2 
cents :-)
