I'm making an IRC bot. I'm using alarm (for now?) to make it check the request queues.

I have no clue why/how, but when I run the code (which calls the sub, Alrm, manually once at startup) it works fine until the alarm next expires (and it works fine if I 'kill "ALRM", $$').

I've tried using Time::HiRes (setitimer, alarm) and Perl's core alarm, and I've made sure there's no sleeps or anything else in my code, just in case. I've tried with return 1 and 0.

I've narrowed it down to the sub ending, using prints.

Code: 

sub Alrm {
        &M(0, $cfg->{staff}, "Received SIGALRM.");
        my $sth1 = $dbh->prepare('SELECT COUNT(*) FROM rand_reqs WHERE
+ acted = 0');
        $sth1->execute();
        my @ary = $sth1->fetchrow_array();
        my $reqs = $ary[0];
        if ($reqs) {
                &M(0, $cfg->{home}, "There are $reqs requests in-queue
+.");
                &M(0, $cfg->{staff}, "CHECK QUEUE.");
        }
        $SIG{ALRM} = \&Alrm;
        alarm(30);
}
