Memsql docker cluster in a box with mount volume

Hi,

I have a memsql docker container with data,
I want to backup the data on this container so I tar the files under /var/lib/memsql.
while tarring this folder I see the following messages:

tar: /var/lib/memsql/f848db91-5ad8-4361-90d4-5d82a845b95f/data/memsql.sock: socket ignored

When I use this tar file to upload new docker with the same data I get the following error:

01907167 2019-10-29 07:31:14.203 ERROR: Can’t start server: Bind on UNIX socket (36)
01907565 2019-10-29 07:31:14.203 ERROR: Do you already have another memsqld server running on socket: memsql.sock ?
01907889 2019-10-29 07:31:14.203 ERROR: Failed to start MemSQL

the tar file exclude the memsql.sock files and when I untar the data and start new docker with these data i failed with the error:
Do you already have another memsqld server running on socket: memsql.sock ?

how I can fix this issue?

Thanks,
