Sorry, I meant to say updatedb when mentioning the process name.

Eugene, 

 

Seeing that's when the daily cron takes place, maybe one of the daily cron
tasks.  Are you running any other utilities (like sysstat) that might give
you more information.

 

If the tasks that run at 4:am are intensive, you will see latency.  If those
tasks require DNS lookups, then it would explain the incrase in traffic.

 

That's where I'd start looking.

 

Gary

Hi folks,

I would appreciate if somebody could give a hint about what could be
happening at 4 am in the morning with the server.

This is a graph for it and as one can see there's a hell of activity and a
significant increase in delays. I have only two tasks scheduled to run at  4
am in the morning and they are just log rotation and updated processes. They
don't take even a minute to run.

Eugene
