     No, it's impossible - the machine in question is fairly heavy  
loaded Internet server resides
on remote Data Centre. I'll upgrade it after 6.2-R, and for now I'll  
try to sumulate similar network activity
using my laptop with fairly recent RELENG_6.

     There is an /usr/ports/net-mgmt/ng_ipacct port had built and  
installed, and me set up a Web server
moderate-to-heavy loaded. All worked fine, and I was happy. :)

     But some time after I have raised number of processes Apache  
initially starts up to 256, and kernel
goes to panic under some network load -- as I'm not monitoring that  
machine 24x7, I can't precisely
say what kind of load crashes the machine.

     ... Only two things are infinite - the Universe and human  
stupidity, and I'm not sure about the former.
