Hello, I wonder if anyone can make sense of this, Ive had this shop running for over 2 years without any problems at all until this morning where as I received this email from the hosts saying the database was suspended and has to be optimized, but I dont understand what is causing the overload from these logs...

Just wondered if anyone else can make sense of this, it is something that happened in the early hours of hte morning when there is the least amount of activity, so im really confused.

If anyone can spread any light it would be greatly appreciated
Thank you
Sam
