[OmniOS-discuss] Win 8.1 NFS client

[Valrhona]

And per the Illumos.org documentation, the fix is pretty simple:

svcadm clear nlockmgr

Any insights as to why this is happening, and what can be done to prevent it?

In Win 8.1 Enterprise, I am using:
mount -o fileaccess=777 192.168.1.123:/mydata g:

In Linux:
mount -t nfs4 192.168.1.123:/mydata /mnt/mydata/

In OpenIndiana:
mount -F nfs 192.168.1.123:/mydata /mnt/mydata/

Is there anything else I should be doing? Again, these commands have
worked for years; only after introducing Win 8.1 has the NFS dropping
out been a problem. Thanks!

By itself "svcs -xv" will not show any output if things are working.  The SMF service in question (here shown working properly) is:
