"ping timeout " and " software caused abortion " are 2 different issues and problems....
as i said before, the providers firewall could be affecting your ircd server and the firewall could be giving the " software caused abortion " - "ping timeout " is either the fact that the config file needs tweaking to ping the clients more often to check they are still active or ur ircd server simply doesnt have the bandwitgh it needs to operate on, or finally the fact that ur clients are doing stuff which is " hogging " or taking up all there bandwith, in any rate (if im wrong / missed something im sure someone else will say)

as for the link you pasted, well thats very well etc, but i dont see how that is causing a " software caused abortion " :-
Msn TCP ports: 1863,6901,6891-6900 UDP: 6901
mIRC Chat TCP: 6660-6669 UDP: none
there are no port matchs there for any on either tcp / udp, even if there was/ is it would only " hog " or fight for connection / bandwith, but how is that different from any other time O_o
Tiberian sun is there becuz i play it online. - i have ISDN 64K connection, my clan m8s are all german they are running dsl and cable connections, if we play a game just for us, its very fast if one however, is on MSN the game lags by 0-2secs desipte the fact they are on dsl / cable. - tiberian sun and msn use the same port. *no brains required here*
anyway to see if ur unreal ircd configs change them to test,
class clients {
pingfreq 90; <--- change that, althou lower than 90 secs aint recommended
