Yes, you are very welcome, I hope that I may see your server in great condition for myself soon, (but thats not until I get a new PC).
Although it seems to me that all server's crash eventully, so don't expect it to be up for weeks on end, my advice would be to restart every week or so, that way it probobly won't crash as often, and it will not lag as bad too. Honestly I don't know what causes ded serv's to crash out of nowhere, but one thing I do know is that it mostly happens after you add wads.
Also a small things of wad do's and don't's for a ded serv
1. No SF94 serv
2. No levels with a cutscene before you enter it (such as SRB2rock or Tortured Planet)
3. In GFZ huge watch out for the sky changers and some teleporters, they can crash the game
Those are just a few things to worry about in a ded serv, but if your serv is wad free, then you should be good, unless some thing happens to your computer or the MS.
