Set size changed in all_sites for LMS container

I’m getting the following error in LMS container logs, have restarted the container multiple times, restarted docker as well, and installed requirements as well but it doesn’t go away any suggestion?

I don’t have any other edx release configured on my local devstack, just juniper.
