Where do you set PERL_SIGNALS to unsafe?

Is Interchange in PreFork, or fork-on-demand? What is the MaxServers 
setting?

What operating system, distribution, kernel version?

Are you using suEXEC or a set-UID CGI binary? It sounds like you're using 
the compiled C-based vlink, right?

Can you see the "connection reset by peer" message in the logs? If so, is 
there any pattern to the URLs that it happens on?
