A possible cause for the problem is the new open-sourced NFS lock daemon.  (It may have some residual bugs.)

I have MacOS 10.6 and 10.9, and I'm seeing occasional problems as well.

If you get it going offline, please utter:  "svcs -xv" on the OmniOS/Illumos box and see if anything reports as being faulty.  I've seen the NFS lock manager flake out.  By itself "svcs -xv" will not show any output if things are working.  The SMF service in question (here shown working properly) is:

hdc(~)[0]% svcs -xv nlockmgr
svc:/network/nfs/nlockmgr:default (NFS lock manager)
 State: online since June  9, 2014 08:33:04 PM EDT
   See: man -M /usr/share/man -s 1M lockd
   See: /var/svc/log/network-nfs-nlockmgr:default.log
Impact: None.
