--- Comment #33 from Lenore Gilbert <lenore@lenoregilbert.net> ---
Just wanted to add that I've also been seeing this crash every ~24h on the
latest patchlevel of 15.0-RELEASE.

Some things of note:
* I'm using NFSv4
* There is a single client of this NFS share, which is an Ubuntu Linux client
* This worked without stability issues in 13.x-RELEASE and 14.x-RELEASE prior
to upgrading to 15.0-RELEASE

I first tried the patch in a similar bug here with no change in behavior:
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=292884

However, after applying the 3 patches from this bug (in addition to the patch
in the bug linked above) I've now had 48h of stability for the first time since
updating to 15.0-RELEASE.

Let me know if there is any additional information I can provide and thanks for
the fix!
