I’m getting an error in the log every 10 mins:

I’ve also had a failed snipe, with the following trace:

This auction was not won by anyone else, so it’s not an auction value problem. I’m also experiencing issues with ended BIN auctions not getting moved to completed tab, and tabs generally not being saved.
Any ideas?
