Exchange error 116/EXOLEDB

Im getting the following error when starting up exchange:

so a couple questions - is this a big deal? the server appears to be working normally, and i havent noticed any unwanted behavior.

what do i need to do to fix it? ive found a couple KB articles like http://support.microsoft.com/kb/316622 with some instruction, and they seem potentially hazardous. What would i be looking for WRT SystemMailbox{GUID}? Ive found the systemattendant and smtp mailboxes, but not that one.

Exchange 2k3sp2, Server 2k3sp2

Does the error correspond with anything (restarting the server, moving a mailbox, accessing via OWA)? How often are you getting it?
