[Zope] Zope refusing to serve our large files (180M+)

None. Zippo. Squat. I've turned on 'ALL' logging in zope.conf for all
logs. All I get is a simple entry in the Z2.log thus:
128.214.209.35 - cwilton [08/Dec/2005:18:38:46 +0300] "GET
/dali/downloads/180M.tar HTTP/1.1" 500 272 "" "Opera/8.5 (X11; Linux
i686; U; en-GB)"

And an equally unhelpful entry in the trace log:
------
2005-12-08T18:45:23 B 1131651340 2005-12-08T18:45:23 GET

Nothing at all in our error log (stderr and stdout for zope process
redirected to logfile) or the event log.

Thanks for the advice on ftp; I might look at newer Zopes, but we'd
rather not have to use zope's ftp (for reasons including those you
pointed out), as our content should be reachable through the http
server; I'd rather tackle that problem.

Bummer. Anyhow, see above about wanting to avoid ftp...

Sorry, that was a bit muddled, what I meant was when I list dir
contents using ftp, I see my LocalFS object listed there with 'owner'
Zope, 'group' Zope, and mods 660 as far as ftp is concerned. The
security settings in zope are the ones that I seem unable to change
for a LocalFS object. Well, they're clickable, but the changes don't
seem to stick. Again, bummer, but again, I was hoping it'd be
unnecessary...

Any obvious config settings I might be missing?

Thanks,
Chris
