[BUG] Some connections to MySQL database fail

[raph-topo]

Tag/version of Container Images
0.4.5

Using mariadb:10.5 as configured in docker-compose-mysql.yaml works, but Docker logs for database: still spit out some mysterious lines:

[Warning] Access denied for user 'root'@'172.30.0.4' (using password: NO)
[Warning] Access denied for user 'root'@'172.30.0.3' (using password: NO)
[Warning] Aborted connection 5 to db: 'mailman' user: 'mailman' host: '172.30.0.3' (Got an error reading communication packets)
[Warning] Aborted connection 18 to db: 'mailman' user: 'mailman' host: '172.30.0.3' (Got an error reading communication packets)
[Warning] Aborted connection 28 to db: 'mailman' user: 'mailman' host: '172.30.0.3' (Got an error reading communication packets)

(172.30.0.4 is mailman-core & 172.30.0.3 is database)

I am unsure what is causing this, probably need to run this with Mailman CI and see what's going on.
