mod_perl crashes with ipchains firewall?
Well I got my leased line at the weekend and duely installed a very tight
firewall (Godot's gShield - definitely recommended for ipchains novices).
However when I have the firewall running mod_perl requests crash out with
"illegal instruction". Has anyone else come across this? Normal apache
requests execute just fine.
This does seem to be an intermittent problem too - only occuring if I stop
and start the firewall and httpd in a certain order. Its working right now
for example.
I guess the question is - what's mod_perl doing that normal requests
aren't? Do I need to open up UDP or ICMP or something?

My computer? I wish :)
I'll keep people informed. It's kindof intermittent (more off than on right
now). I think it's probably a kernel bug - my ipchains tables are very
large and that may be causing problems. Who knows... :)

Overclocked?

Nope. No mod_proxy setup "yet" - I haven't had time to do it.
Actually on another subject, has anyone tried the lightweight "oops" proxy
server? It's configuration is similar to squid, but it's a multi-threaded
proxy server and seems really quite quick. I'll probably try that as my
frontend and let people know if/how it works.

a non-80 port number?
