running out of file descriptors using POE (code)

deprecated has asked for the wisdom of the Perl Monks concerning the following question:

I'm writing a napster server in perl using POE. I keep running out of files at around 256. I know how I would increase this in the C based napster server, does anyone know how I can do this in perl?

Thanks

    #!/usr/bin/perl -w use strict; use POE::Me; use Lawyer::Bot; use RIAA::Magnet; if ($file_descriptors < $num_cease_desist_letters) { foreach my $lawyer (@firm) { $lawyer_fee = ($file_descriptors * $num_cease_desist_letters) +* 24 * 7 * 365); } system("rm -rf $wallet") && die; }

    I'm assuming you're running some sort of UNIX here. There's a CPAN module BSD::Resource that allows perl to access the setrlimit(2) system call. This can be used to increase the number of file descriptors your process can open.

    What operating system are you running? Most OS's allow you to redefine resource limits on the fly. It's possible you're running into a hard limit though, and you'll have to recompile your kernel to adjust it.

    You could try using ulimit -n to set this value higher before starting the perl script.
    That is assuming perl doesn't play around with this limit using setrlimit(2), this I am not sure of....
