Database errors? I get e-mails every time the server generates a database error, and I haven't seen any in a long time aside from the usual nightly downtime when the backups run.

I'm unfortunately going to need more information to track this down. A screenshot might be a good place to start, as well as information about the trades being made (who it's from, who it's to, what's offered in the trade).
