Some techniques to deal with problems in Perl Memory Usage
Try searching google for "memory leak" perl. Here is a summary of articles found on April 7, 2004:
- Unfortunately some programmers don't think that memory leaks are important. Some complaints about Perl, or it's modules, leaking memory are met with responses like Buy some ram [1]
- [Valgrind] is GPL'd system for debugging memory use in X86-Linux programs. But it won't tell you where specifically in your perl program you are having problems.
- Here is a routine that might help to monitor perl memory usage from http://mathforum.org/epigone/modperl/fumtolblal

        sub p {
	        my $mesg = shift;
	  print "$mesg used memory = ".(BSD::Resource::getrusage)[2]."\n"
	}

        sub p {
	        my $mesg = shift;
	  print "$mesg used memory = ".print GTop->new->proc_mem($$)->size."\n"
	}

Possible memory leak problems with the s/// operator in perl 5.8. http://www.gossamer-threads.com/archive/mod_perl_C1/modperl_F7/%5Bmp2%5D_Regex_memory_leak_introduced_in_5.8.1_causes_havoc_in_mp2_P107089/
Some advice about reporting perl memory bugs: http://lists.freebsd.org/pipermail/freebsd-ports/2004-January/008136.html
Devel::Leak and Devel::LeakTrace?Create are mentioned on http://use.perl.org/~pierre/journal/15657
- This person developed Data::Structure::Util to find circular references
- He has a great way of listing his email address: pierre reversethis-{moc.ognatof} {ta} {sinedp}
- ActiveState?Create's Perl Package Manager (PPM) does not seem to know about this module.

ActiveStates?Create PPM does have Devel-Leak. Devel-Leak's output is not too useful if you do not have a perl compiled with the debugging flag.
