}
I don't think that's doing what you think it does. As far as I can tell the bare $repeater doesn't do anything. You probably want something like
if (system(@args1) != 0) {
logEntry ("No repeater.pl is running, attempting to re
+start");
$repeater = Proc::Background->new('/etc/squid/repeater
+/lib/repeater.pl');
}
Also, Proc::Background has functions for checking whether or not the process is still running, so you may want to use those instead of shelling out to pgrep:
if (!$repeater->alive()) {
logEntry ("No repeater.pl is running, attempting to re
+start");
$repeater = Proc::Background->new('/etc/squid/repeater
+/lib/repeater.pl');
}
Of course that would not detect a process that was already started when your watcher begins. (But in that case you'd currently have 2 running processes anyway since you unconditionally start one with the initial Proc::Background->new call.)
