I just looked at my recent log entries and found a bunch of:

Could this be an attack or sign that someone has broken in? There is more then one IP adress on each entry showing from more then one country.

I'm going to submit a ticket to my hosting company.

Could someone hint to me whether this is a reason to freak out or not?
