Hello, I've had problems with <Perl> sections causing leaks with graceful restart, at least with some versions/setups of mod_perl. I thought the problem should be noted in the guide.
A patch is attached for: http://perl.apache.org/docs/1.0/guide/troubleshooting.pod.orig I no longer have my test code, it was a while ago. Here's the link and mail exchange that confirmed my tests: http://aspn.activestate.com/ASPN/Mail/Message/modperl/304620 > >> > I have a static Solaris compilation, and have the same problems > >> > where the parent seems to grow by 1M each HUP. > >> > >> that's strange, do you have PerlFreshRestart On or some <Perl> sections? > >> otherwise, kill -HUP with a static modperl is a noop. > > > >You got me! I have <Perl> sections ... but I didn't know > >it was such a crime. Pretty bizarre behavior if you ask me. > > it's not a crime, but if you're running Perl code during restart there's a > strong chance you'll be growing the server size. i agree 1M is bizarre > though.
