I've recently been graphing performance statistics (nagiostats, mrtg) and as you can see by the two attachments (day, week), it's rather surprising.


I'm sorry I can't shed much light on it, but I've seen the same
behaviour myself, albeit on my system the service check latency
wouldn't start increasing until after a week or two but you're right -
the rate of increase when it starts is quite alarming.  I've recently
culled a lot of checks from the system which has ameliorated the issue
for the time being, but it would be good to get it fixed properly.
