How to tell what's causing CPU spikes?

Jeff x

Since updating to 9.508-10, I get CPU usage spikes at intervals. I'm thinking this may be a bug which is causing a service to restart but I haven't found anything yet.

The image below shows CPU usage before and after the update (around 09:30):

 

I've viewed all of the logs but I haven't been able to identify what's causing the spikes.

Any suggestions?

    Hi Jeff,

    I think you should console to UTM (ssh, telnet), log on UTM then check cpu use with command: top

    On screen, you can see service are running on system. From that, you know cause CPU spikes.

    Hope it can help you

    Thanks for the suggestion. I already did that but I wasn't able to pin down the cause from what I was seeing on the screen.
