Server regulary crash due to harddisk suddenly filling up (included log)

[Shadefox]

Error:
System.IO.IOException: Not enough diskspace (*translated*).

Just a snippit and not really the error I belive.
I run under win xp pro(waiting for my new win2k3 server)
got about 86 gig free diskspace (runuo only application I run + client)

usually it works fine, But suddenly server crashes from time to time, and then, instead of 86 Gb diskspace, it shows 16 kb down to 0 free diskspace.
There is no specific action taken to make it crash, it just suddenly does.


Any clue on this one? (alse tried reinstalling from scratch, just got the crash again)

Thanks for any help!

***Edit**
source of problem located, in the UOgateway\temp\ directory I get 3 folders and 3 files named something like "FBg7153hsghdB002388" (just randomly guessing for letters and nr's" as I can no longer acsess the folder du to windows hangs.
anyone help me out a bit?
these temp files takes up a whopping 86 GB.... Virus scans shows clean system.

I believe that was a bug, back a few versions ago.

Update your UO Gateway, and avoid shards with custom patches.
