I don't tend to use NFS on my systems that are running head, so I
haven't had occasion to test this as stated.

However, I just completed my weekly update of the "prooduction" systems
here at home, running stable/11.  And I find that lockd seems to be ...
claiming that all is well, but declining to run (for long).

To the best of my knowledge, that was not the case until this last
update, which was from:

FreeBSD albert.catwhisker.org 11.1-PRERELEASE FreeBSD 11.1-PRERELEASE #316  r319566M/319569:1100514: Sun Jun  4 03:54:41 PDT 2017     root at freebeast.catwhisker.org:/common/S1/obj/usr/src/sys/ALBERT  amd64

to

FreeBSD albert.catwhisker.org 11.1-BETA1 FreeBSD 11.1-BETA1 #322  r319823M/319823:1100514: Sun Jun 11 03:56:10 PDT 2017     root at freebeast.catwhisker.org:/common/S1/obj/usr/src/sys/ALBERT  amd64

The "glaringly obvious" symptom in my case is that I am now unable
to (directly) save an email message from within mutt(1) by appending
it to an NFS-resident file.  (Saving it to a local file, then using
cat(1) to append that to the NFS- resident file & removing the local
copy works....)

After a few variations on a theme of:

albert(11.1)[5] sudo service lockd restart
lockd not running?
Starting lockd.
albert(11.1)[6] echo $?
0
albert(11.1)[7] service lockd status
lockd is not running.

I finally(!) thought to ask ktrace what's going on (as tailing
/var/log/messages was completely unproductive, even after enabling
rc_debug).

So I tried: "sudo ktrace -di service lockd restart"; upon exanimation of
the output of kdump(1), I see that the trace ends with:

  ...

  2811 rpc.lockd RET   sigprocmask 0
  2811 rpc.lockd CALL  exit(0x1)

Then, when I tried to send this message, I started getting more whines
from mutt(1).  I finall gave up and rebooted from the previous
environment:

FreeBSD albert.catwhisker.org 11.1-PRERELEASE FreeBSD 11.1-PRERELEASE #316  r319566M/319569:1100514: Sun Jun  4 03:54:41 PDT 2017     root at freebeast.catwhisker.org:/common/S1/obj/usr/src/sys/ALBERT  amd64

and lockd is running:

albert(11.1-P)[2] service lockd status
lockd is running as pid 629.
albert(11.1-P)[3] 

so mutt(1) is not pitchng a hisssy-fit every time I try to save or
send a message.


In light of the above, I have Bcced: this message to current@ (where
the thread originated) and sent it (and set replies) to stable at .


I have a test system, last updated to stable/11 as of mid-October
last year; lockd was running on it, as well (which is why I tried
going back to last week's image).  I'm happy to update it to points
where lockd may be broken, if it might help figure out what's broken
and how to fix it.

Peace,
david
