Earlier in the week I tried running a buildworld on a 11.1-RELEASE system that had /usr/obj mounted via nfsv4 from a 12-CURRENT server. After some time, the build hung I saw this message start repeating in /var/log/messages: May 15 08:23:03 rstone-server kernel: nfsd server cache flooded, try increasing vfs.nfsd.tcphighwater In 12-CURRENT, sysctl vfs.nfsd.tcphighwater defaults to 0, so I have no idea what a reasonable value to set would be. Any advice?
