Dear Maintainer,
I have the same experience with NFSv4. My customer run PHP7/laravel application
on server which I maintain. I put data directory with pictures and caches to
NFSv4.
Log is filled with nfs4_reclaim_open_state: Lock reclaim failed! and after
while system is unusable I can login with ssh but apache don't serve any pages
with strace I cann't see anything.
Only reboot helps. I try upgrade to 4.14.31 and still the same. Only help is
switch to NFSv4 local_lock=all.
Regards
Dan Smolik
