But I'm having this problem with service checks, not host checks. I do have the concurrent service check limit set to 30 and I wonder if that is affecting the scheduling of service check retries but, if so, I would think it would make the retry interval longer, not shorter than specified. Does anyone know if service check retries are subject to the concurrency limit?

Any idea what could be causing this? Hi Paul, I have been looking into this myself the last couple of days. Nagios does "on demand" host checks, the reason for this is explained here http://nagios.sourceforge.net/docs/3_0/hostchecks.html It basically means Nagios executes the host check when it thinks it needs to do so. You could alter the cached host check horizon (http://nagios.sourceforge.net/docs/3_0/cachedchecks.html) so Nagios does "on demand" checks less frequent and uses older host results instead. What I'm personally wondering is whether "on demand" checks should count as retries? Because this is the case at the moment and it makes the parameter 'retry_interval' virtually useless.

[Nagios-users] Problem: Nagios service check retry interval shorted than configured.
I have nagios core 3.2.3 built on SuSE 11.1 and I've been noticing apparent problem with service check retries. The normal check interval is set to 7.5 and the retry interval is set to 1 minute. I'm seeing entries like this in the log: [03-02-2011 16:44:39] SERVICE ALERT: aps11;Extra_01.20;OK;SOFT;2;SELRC OK [03-02-2011 16:44:29] SERVICE ALERT: aps11;Extra_01.20;UNKNOWN;SOFT;1;SELRC UNKNOWN - Timeout (130 sec.) reached [03-02-2011 13:28:19] SERVICE ALERT: aps14;Extra_04.15;OK;SOFT;2;SELRC OK [03-02-2011 13:28:09] SERVICE ALERT: aps14;Extra_04.15;CRITICAL;SOFT;1;SELRC CRITICAL Why is there only 10 seconds between these pairs of checks? Sometimes I see a 20 or 30 second difference sometimes 60 seconds. Most of them are less than 30 seconds. It's very inconsistent. Any idea what could be causing this?
