I am having the exact same problem with all of my characters. Every 15-20 minutes I get the message "Lost Connection to Mapserver". Seems to happen most frequently when I'm in a mission map, if that makes a difference. I'm on the Freedom server. I've tried turning the graphics up, turning the graphics down and turning all of the sound to 0%, to no avail.
Here is the info from CoH Helper.
