A site tree's XML structure must not be empty

[Grant Dunham]

Has anyone discovered why the site tree's XML structure becomes corrupted?
I know how to correct the problem when it happens, but I don't know why 
it happens and how it can be prevented.
It just happened to our server again yesterday. This problem seems to 
have started about 6 months ago. I did a fresh install of Frontier on a 
Windows 2000 box hoping I had messed something up on the old install. No 
luck. Still get the error sporadicly.
I save a copy and replace the root files weekly thinking age may have 
something to do with. That seems to have reduced the number of 
occurances - but has not eliminated it.
The last time this thread surfaced (about a month ago), I know several 
other server admins indicated they too were experiencing this problem. I 
would be much happier to know how to prevent the problem in the future.
