Now see that's something I never thought about. A bizzare 'bug' that's not directly related to the game itself. How common is this issue elsewhere in the server? I know it's perhaps a shuned topic but a little discussion on the typical exploits and the patches around them would be nice here. > Checking for multiple connections from the same IP is a good start, > but doesn't save you from DDOS.

Well I've worked with threads before, so I would be curious how to use them to relieve this problem, but only perhaps as an example. > Actually, i"ve got file_open and file_close functions that handle the > null pointer, write the files to tmp location then copy it to the > correct location.

I'm quite interested in this, code and post away if you would. Your knowage of the subject leads you to generate a better solution this way then not. Tony
