Thanks for the reply, but sometimes I don't know where is the code that cause the infinite loop. Is there such as thing as perl configuration file, to set the execution time for any code, any where in the program just like php.ini file. Thanks.

You can set an signal to go off after X seconds with the alarm* function:
#!/usr/bin/perl
use strict;
use warnings;
my $timeout = 5*60; #timeout after five minutes
eval {
local $SIG{ALRM} = sub { die "timeout\n" };
alarm $timeout;
#stuff you want to run in under five minutes
};
die unless $@ eq "timeout\n" if $@;
