I've had ongoing problems with a 5.4 box that does boatloads of file IO both on NFS and local disk (doing weird things with 10 to 12 GB of Apache logs daily). NFS seems to go away for a few seconds (the filer is unpingable), then return. Despite the 5.x branch's known problems, I had attributed this to the fact that I'm using bge NICs. I moved most of this log processing to a 6.1-RELEASE box last week (on identical hardware), and I've seen none of the timeouts. Hardly scientific, but my $0.02 nonetheless I'm using HP DL380-G4 servers (onboard bge, ciss RAID), with a BlueArc Titan for NFS. Of course, I'm not running nfsd on the FreeBSD boxes, they're just clients. -- Paul Chvostek it.canada http://www.it.ca/
