Unpredictable service check times fixed?

[Mateo Carr]

Thank you for all of your help.

I am running nagios on OS X. There were a couple of challenges to  
getting everything compiled and happy, but nothing insurmountable. It  
is a really great piece of software, and we are looking forward to  
getting it fully deployed.

It turns out that my issue was actually that I was bouncing off of the  
user maxproc limit and not running out of memory as previously  
thought.. I determined this for certain by making a small change to the  
source so that it says which errno condition is set.

Now that I have worked around that issue, I have one more quick  
question, which is related to this situation being triggered to begin  
with. It seems that over time the service checks all get clumped closer  
and closer together. I have been sampling the number of nagios user  
processes every 5 seconds, and over time a pattern like the following  
emerges: 9 9 9 9 7 7 7 7 7 7 7 7 48 170 64 76 33 31 21 47 55 43 21 17  
13 9 6 6 6 6 ......etc.... This grouping of checks is confirmed by  
looking at the scheduling queue. My question is has anybody else  
observed such behavior? I realize that I could set the  
max_concurrent_checks manually as a workaround, it just that I would  
prefer to let nagios sort it out.

Thanks!
