And another one crash, achieved by running the following in the shell.
Ran several times, as see from dmesg:
$ op=stop; sudo /etc/init.d/nfs-common $op; \
sudo /etc/init.d/nfs-kernel-server $op; \
op=start; sudo /etc/init.d/nfs-common $op; \
sudo /etc/init.d/nfs-kernel-server $op;
Repeat several times ;)
The dmesg output:
