which map was it loading?
do you have the bf2 special forces expack?
did the map finish loading then crash?
if you do not have the bf2 special forces xpack it may have been crashing for you on cement factory night map,cuz youd be missing files which make nightvision work.
the cement factory night map may have been running for quite some time due to lack of players,need them players to make the server play different maps.
