RMGir, and what i do now? Sorry, but my english is weak

Where i have to add?: $SIG{CHLD} = 'IGNORE';

Add it right at the top of your script.

use warnings;
use strict;
$SIG{CHLD} = 'IGNORE';

Don't apologize - your English is far superior to my Polish (thank you, Google Translate, for helping me identify that as Polish :) )

I think all you need to do is add the following lines just below your last "use" statement:

use Config;

# copied from perldoc Config
my %sig_num;
my @sig_name;
unless($Config{sig_name} && $Config{sig_num}) {
    die "No sigs?";
} else {
    my @names = split ' ', $Config{sig_name};
    @sig_num{@names} = split ' ', $Config{sig_num};
    foreach (@names) {
        $sig_name[$sig_num{$_}] ||= $_;
    }   
}

# ignore child signals, automatically reaping child processes
$SIG{$sig_num{CHLD}} = 'IGNORE';

Of course, you'll have to test this, but I think it might solve your issue.

RMGir, your way isn't working.

jjimmy, how is it failing?

Is there an error in my code, or is your program still failing to fork in the same way it was before?

If it's still failing to fork, it's possible that there are too many php processes still running at one time...

Do you know how how many php processes are started before fork fails? Do all of those php processes finish running, or are some of them or all of them still running when the daemon program dies?
