For the past few nights around 3:30AM I get an alert like this one.
NDO CRITICAL - oldest ndo file is 92 seconds old, 19 ndo files
backlogged
In five or ten minutes I get a recovery message and all is well
until the next night. Any idea why this just started happening and
how I can fix it? I recently increased the number of hosts we have
but it is still small (122) and the number of checks is also low
(865). I just upgraded last night to 3.3.2 on my master server.
The housekeeping is kicked off in the early hours, so it is probably
database cleanup activity that is causing slow responses.
See the mysql tuning documentation and see if that helps:
