SQL error 490 on version 12.0

Yesterday while surfing/streaming while updating a game over p2p. My untangle box "kinda" failed on me and came up with these weird messages.(very slow line speed)
But in essence it was SQL error 490. I rebooted it once. Still error. So I shut it down for like 15 seconds with no power.(switched off power on the PSU after shutdown) And started it up again.
And it's all good again. Not sure what happened.
This is on untangle version 12.0(clean install) with the rolled out updates for version 12 the day before.

Where was the error shown?

Post the entire error.

I got them on the middle of the screen when I logged on to the web gui.
How do I find these errors again? I'm not very familiar with Linux systems :(
Is it possible to fetch them in the reports somewhere?

If you are not seeing the error now, most likely it was temporary due to the p2p traffic.

Ye. As I said it went away after I shut down the router for like 15 seconds.
And while that error was up. It's the first time I have seen the cpu at around 5% load instead of under 0.5% load.
This is on a home network. 5-6 ppl under normal use. The untangle box have registered around 24 devices in total(with guests)



The box is a I3 3.5GHz dualcore cpu on a Asus CS-B Motherboard. 8GB ram and a 60gb ssd(500Mb r/w)
2 Atheros 9380 wifi cards installed and 2 quadport intel i340 cards. (Only using one of the intel cards atm.)
Rest is hooked up to a 16 port switch. Only got a adsl 20/1 line :(
