I have an x86_64 machine running RHEL5 but with the mod_perl 2.0.3 from Fedora 7.
Without Linux::Smaps installed, Apache2::SizeLimit thinks my processes are taking up 300MB and terminates them after every hit. ("top" thinks so too, but "free -m" quickly proves that's untrue.) With Linux::Smaps, Apache2::SizeLimit simply doesn't work at all, because Linux::Smaps apparently doesn't work under x86_64. See this RT bug I filed against Linux::Smaps: http://rt.cpan.org//Ticket/Display.html?id=29803 I do have a kernel that supports smaps, 2.6.18. -Max -- http://www.everythingsolved.com/ Competent, Friendly Bugzilla Services.
