Version: 07.04.01 

Below error message reported last night by multiple people on one of our portals.

All other portals were up and running but were very very slow

Looking in event viewer this morning I can find no evidence of this error or anything else of concern.

I am concerned this can/will happen again and need to know where to start looking for more information on the issue and where to find it, any help would be greatly appreciated.

for some reason, the site fails to load the list of pages.
This might have been caused by poor database performance resulting in a timeout.
What is the size of your database files?
