We are definitely seeing problems with nfsv2 and either tcp or udp connections. We have tried the -r=1024 fix for udp and that didn't help. We use the 2.2-stable box as an NFS client to a NetApp NFS server. After a little while, the FreeBSD box gets into a state where any command that causes NFS activity hangs, including a simple "df". Once in this state, the command can not be killed, even with "kill -9" from root. I am gonna start comparing the 2.2-stable sources with 3.0-current sources to see if there are any obvious fixes. If anyone has any other ideas, please let me know. We have an immediate desire to get beyond this. ;-) Chris On Mon, 22 Sep 1997, spork wrote: > Is it just me or is there another bug involving 2 FBSD machines running > -stable and nfsv2 or v3? > > In the above situation, if machine A is exporting a directory to machine B > and machine A dies unexpectedly, you cannot umount the nfs-mounted > directory; the command just hangs forever.
