I reckon this is most likely the cause of the problem. They race with each other for write access to the files.

well two containers are sharing states through volumes, but they use different logical databases inside the DB containers

I might have to check that, I have been copying docker-compose files around...

serge

if they don't share state (e.g. database files through volumes) then the problem should be somewhere else I think

serge

are you using official mysql images from dockerhub?

I have currently 3 mysql running, with max 4 DBs on one of them
