[CRIU] LXC DUMP ERROR

[beproject criu]

I am trying to dump LXC container using following command

/sdcard # criu dump --root /usr/local/lib/lxc/rootfs/root --evasive-devices
--tc
p-established --file-locks -n net -n mnt -n ipc -n pid -vvvvvvvv -D data -o
dump
.log -t 79

but i get the following error :

Error (mount.c:517): Mount 58 (master_id: 12 shared_id: 0) has unreachable
sharing

I have attached the dump.log file with the mail containing full log.

Content of mountpoint are:
