4.0 is Very Olde at this point, and amd64 in 4.0 was not quite fully
baked yet. It is definitely not what I would choose to run in
production. (I don't run a fileserver per se but I do have some
machines with real load on them. I moved them all to -5 ages ago.)

If I were setting up a new fileserver right now I'd put 6.0_BETA on
it, even in production. There may be some problems still, but there
are two overriding considerations vs 5.1_STABLE: (1) a pile of
vfs-level deadlocks have been fixed (not all the fixes can be applied
to 5.1_STABLE) and (2) Manuel Bouyer's new quotas that don't need

I've had pretty good luck over the years using -current in production,
too. FWIW. Good luck trying that with That Other OS. ;-)

Do you have the details for the quotaoff panic? Although if it was
caused by hardware it may not be much help.
