I've checked the logs and there is nothing to indicate a problem.
What sort of error message are you getting?
I have monitoring the server over the past few days and found that it is coping well with the increased traffic. The only time the server is sluggish or when database error messages appear is when it is doing an auto maintenance routine which is processor intensive. This last a few minutes every 5 hours.
The rest of the time, the server is fine.
