Hi Anders,

I'm experiencing this problem on Linux RedHat
Enterprise Edition version 3. 
I know that this OS is pretty obsolete, and nobody
should be using it now, 
but I don't have a choice here.  But at least I
installed kernel 2.4.29 :) 
The openssh-server version is 3.5p1-6

Do you remember if the Alpha with reverse DNS lookup
problem hogged the CPU? 
I think the reason why it was making you wait 10 mins
was because it was 
doing some network lookup.  Would reverse DNS lookup
be a factor if I'm 
sshing to 127.0.0.1?  I'm doing ssh root@127.0.0.1
when it hogs the CPU for 
several secs.

Marat
