Re: Apache2::SubProcess subprocess not subprocessing properly

Actually my solution to this problem was pretty rational.  I just turned 
mod_perl off for this particular program.

<Files ~ "(?<!myfork)\.pl$">
   PerlHandler ModPerl::Registry
</Files>

Will I a have possible performance problems?  Sure, but nothing a few 
more $25/month servers can't fix, and it saves me all the aggravation of 
the past months trying to get this to work.

Problem solved!
