--Apple-Mail=_DCCAA671-D7B1-479D-A9B7-A4D0585935DB Content-Transfer-Encoding: quoted-printable Content-Type: text/plain; charset=us-ascii Hi, every few days or so, my -STABLE NFS server (v3 and v4) gets wedged with = a ton of messages about "nfsd server cache flooded, try to increase = nfsrc_floodlevel" in the log, and nfsstat shows TCPPeak at 16385. It = requires a reboot to unwedge, restarting the server does not help. The clients are (mostly) six -CURRENT nfsv4 boxes that netboot from the = server and mount all drives from there. I googled around and saw that others have hit this issue, but I haven't = seen any resolution posted. I guess I can increase NFSRVCACHE_FLOODLEVEL = in the source, but I wonder if I wouldn't simply hit the increase value = after a little while longer...
