So your system doesn't suffer panics and/or deadlocks, or you just
cope with them as "collateral damage" (which, admitted, is less of
a problem with a logging fs)?

If that's the case, would you share the details about what you're using
on that machine (RELENG_7?, 7_0? HEAD?) and which patches
/knobs You used? I have a similar setup on a host which
backs up way fewer machines and locks up every... 3-9 weeks or so.
That host only has about 2GB ram though.

Thanx and regards,
