Hello,

there is a server-crasher going around. You can fix it by setting "sv_allowdownload" to 0.

Could we have a bit more detail into this? This doesn't justify me changing this cvar.

It does, since you should have a FastDL anyway and therefore you won't need that CVar.

People flood CNetChan::RequestFile / CNetChan:: DenyFile until the server will lag or be unable to handle the requests which results in a crash.

If they are using the exploit which I'm describing, you can fix it by yourself by setting the CVar "sv_allowdownload" to 0.

Code:
sv_allowdownload 0 // Enables/Disables downloading from the gameserver. Will not be needed, if you are using a FastDL.

Only if you don't using fast HTTP download on your server you have this problem. But if you have fastdl wia HTTP, you can set sv_allowdownload 0 and all files will be downloaded wia fastdl.
