Re: [Unreal-users] hmm. bug?

[Carsten V. M. <sts...@ts...>]

Might just throw in my cents here.. (this problem was predicted already
before release). Unreal/all IRCds have had a problem with it able to be
"owned"/crashed by a program that spawned heavily many unknown
connections.. We added a fix so no Y:line max clients can be larger than
MAXCONNECTIONS (which in your case is 256) minus 15 (for dns checks, socks
etc). Go edit the Y:line to say Y:1:90:0:241:100000 if you got the
"241" problem. This is for your own good really :P
