Is that all for dropped connections? If there are many more and they come from random external IP addresses, perhaps it is your outside interface (the one that connects to your T-1). I have not used Sonic much, I use Cisco gear and I know in my gear I can see the reliability of an interface in the form of x/x (255/255 would mean the interface has 100% reliability) Perhaps your outside interface is having some problems and a call to your providor would help.
