After the former setup a loop like this can reliably trigger the bug:
#!/bin/bash
while /bin/true
do
lxc exec yakkety-test service rpcbind restart
lxc exec yakkety-test service ypbind restart
cat << EOF | lxc exec yakkety-test -- yppasswd -p ubuntu
ubuntu
ubuntu
EOF
done
At least it seems to hit the same spot all the time:
