Hi all,
Is it possible to limit memory used by perl? I don't want perl program
to eat all memory causing OS to freeze.

I think, one way how to limit memory usage by perl is measure its
memory, you didn't write you OS, so here are some:
for win:
use Win32;
...
my $osname = Win32::GetOSName();
if ($osname eq 'WinXP/.Net' or $osname eq 'Win2003') {
print "memory usage: $1 RAM." if `tasklist /FO list /v /FI "PID eq $$"` =~ /Mems+Usage:s+(.+)/;
} else {
print "memory usage: $1 RAM." if `tlist $$` =~ /WorkingSetSize:s+(d+s+w+)/;
}
for *nix:
http://www.perlmonks.org/index.pl?node_id=336856
or something like that :)
I had similar problems (too big data structure for speed...),
so I limit hash keys to certain value...

Yes maybe :-p
I have prototype that should parse big log files (680MB) converted into
nice GUI apps. It's not nice if the machine totaly freeze during testing.
(linux 512MB/2GB swap).

Hi
Maybe you should relook / think yout app and see where you can make it
more effienct
Kind Regards

P.s. How much memory is the machine using?

account (and maybe per-process, I haven't really gotten into it) limits
on things like memory and CPU.
