Re: Weird processes

every concurrent cgi script uses its own postgres connection in your
case. you're going to run into more serious problems (e.g. empty pages
for no reason) because of lack of possible postgres connections. so,
1) try mod_perl to speed up your perl scripts
2) think about writing a server which would provide cgi scripts with
cached connections; you can $handle->prepare(...) the most common
queries as well.

anyway, it's not a postgres problem. if you wish to discuss that you may
write me in private or try a www-developers mail-list.
