Looks like either your operating system isn't giving moin enough file 
handles (for DOS, this used to be some FILES= stuff, don't know exactly 
how this is for win32).

Or (if concurrent TCP connections also count as open file on windows), 
maybe you did too many requests in parallel and ran out of files because 
of that. Maybe the browser didn't close the connections cleanly, so 
those "files" stayed open until they time out. Maybe try if waiting 
helps (though I don't know how long the timeout is).

Or it is one more strange mod_python effect, then maybe trying fastcg or 
plain cgi helps. Or use moin's standalone server (you can use apache as 
reverse proxy for that if you like).

That's unrelated. If you trigger that, it tells your rather clear that 
you did.

Maybe try to find out what files are open, how many are open.
