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, Lorenzo
