I agree as well, your line is getting shorted to either ground or 
something with the polarity reversed and biasing it into that condition. 
A 9V battery in series with (not across) the line might provide some 
temporary relief when this happens, but its a line problem. Simple 
diagnosis, when it rains is your server wet ? if not then its not likely 
part of the problem or solution.
