If you have the time/expertise to come up with good patches for the
code and are willing to donate these to the project, I'd suggest you
either post the patches or attach them to a bug report. Please
remember that almost all work on FreeBSD is done by volunteers in
their spare time, rick.
I reported PR164933 early this year with a patch, but unfortunately no
one responded.
I've attached the patch against 9-STABLE now.
Please review.
I found also other problems with NFS reliability (can reproduce
consistently) - will discuss tomorrow on freebsd-fs.
Cheers,
Attila
PS: Sorry about the language (ESL) of my letter, I'd like to contribute
if I can.
