  I have the same problem. The server has one jail with nginx and I use ram disk for fastcgi cache.

 /dev/md0 on /usr/home/jails/j2/var/tmp/nginx/fastcgi_cache (ufs, local, noatime, noexec, nosuid, nosymfollow)

After stopping jail mount point is still present. I use VIMAGE too.

May be need CC to freebsd-virtualization or freebsd-net as this issue might be vnet related?
