Nagios Support Forum

I've always thought this was a problem with forking off processes to do the service checks, since the start.

Well, this is a new one:

CRITICAL - Plugin timed out while executing system call

Just sometimes, and re-enabling those checks seems to kick others off that were fine.

I've tried upping timeouts and it doesn't really seem to do anything, 99% fine, then the old connection refused stuff.

Running command line checks all day - work 100% but I will add -v to check this time.

(They are the standard notification commands that come in commands.cfg with Nagios... basically)

Unlikely they are wrong, as they haven't been altered.

That is actually there, I just use nano and you know.. Column width clipping and all that. command_line /usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState: $HOSTSTATE$\nAddress: $HOSTADDRESS$\nInfo: $HOSTOUTPUT$\n\nDate/Time: $LO...

Same old connection refused errors again on the checks I re-enabled.

I'll pm you some logs.

Put debug to -1 as I have plenty of space and 1 was only really showing function calls.

Ah that's better.

Running for an hour or so so far. Not a single connection refused error and everything reporting normally.

Problematic checks re-enabled for the day and logging enabled (debug=1)

All set to email notifications only so shouldn't get too annoying. I'll PM logs to one of you tomorrow probably.

(Please treat with sensitivity)

I'll turn the problematic checks on tomorrow and enable debugging, then update you here.
