Bionic verification
"TEST A" verification was done following steps from bug #1927745, where
the lack of the restart was first found, and that fix is included in
this upload as well.
ubuntu@b-gssd-restart-1928259-1927745-A:~$ apt-cache policy nfs-common
nfs-common:
Installed: 1:1.3.4-2.1ubuntu5.3
Candidate: 1:1.3.4-2.1ubuntu5.3

Problem quickly reproduced:
ubuntu@b-gssd-restart-1928259-1927745-a:~$ sudo ./bz1419280_test_threads
Iter 1
calling stat on '/mnt/test_krb5/foo' with uids 9995 through 10035
reproduced the bug after 1 iterations
ubuntu@b-gssd-restart-1928259-1927745-a:~$ ps axw|grep stat_as
8012 pts/0 D 0:00 ./stat_as /mnt/test_krb5/foo 9995 10035
8036 pts/0 D 0:00 ./stat_as /mnt/test_krb5/foo 9995 10035
8091 pts/0 S+ 0:00 grep --color=auto stat_as
In this state, I installed the fixed packages from proposed. But first, let's
get the rpc.gssd pid:
ubuntu@b-gssd-restart-1928259-1927745-a:~$ ps axw | grep rpc\\.gssd
7854 ? Ss 0:00 /usr/sbin/rpc.gssd
Now upgrade:
ubuntu@b-gssd-restart-1928259-1927745-a:~$ sudo apt install nfs-common
Reading package lists... Done

Not only was rpc.gssd restarted automatically (see new pid):
ubuntu@b-gssd-restart-1928259-1927745-a:~$ ps axw | grep rpc\\.gssd
8886 ? Ss 0:00 /usr/sbin/rpc.gssd
We also got rid of the stuck stat_as processes:
ubuntu@b-gssd-restart-1928259-1927745-a:~$ ps axw|grep stat_as
9550 pts/0 S+ 0:00 grep --color=auto stat_as
