]] Massimiliano Ferrero | If default shell is /bin/dash then all check_procs commands run though | nrpe daemon return a +1 value in the number of processes they count | i.e. if there is one /usr/sbin/acpid process running the check will | return 2, more seriously if there are none the check will return one, | so if the check is used to restart dead daemons this won't be done | anymore. | | The problem is dash-related: this can be easily verified by running

I'm not entirely convinced this is a bug in check_procs at all, if anything, it'd be a (minor, I think) bug in dash. Note that you can get the same behaviour from bash by doing something like: /bin/bash -c "/usr/lib/nagios/plugins/check_procs -vvv -c 1: -a '/sbin/init'; true" where bash won't just exec() a simple command, but will stay around until the last command has run. -- Tollef Fog Heen UNIX is user friendly, it's just picky about who its friends are -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
