But, here's a couple of things you could try to avoid using the NLM. - Do the Linux mount with the "nolock" option. (If Ubuntu has a "locallock" option, that would be even better, but I'm not sure what options recent Linux's have for nfs mounts.) - Download my server patches (ftp.cis.uoguelph.ca/pub/nfsv4/FreeBSD7) and switch to using nfsv4, which has integral locking in the protocol.
