Console Message
22:08:ERROR:MySQL server link has been lost. Trying to reattach to it.
I not know if is normal because mysql run on same thread of core. but is not very good this.
Hmm, if I remember correct this is really old issue, when mysql can't connect to server it causes lag, but I am not sure what can do for that, because I haven't check how mysql works on sphere, maybe the progress could move to backwards to avoid server lagging but I am not sure if it's possible.
Is this still a issue, since we moved to a recent MariaDB version? If it's the case, a possible solution would be to try to connect to the db in another thread, and having an atomic bool inside a GlobalStates struct wrapper to check if Sphere is connected to the db and can run the query.
This partly depends on where the SQL server is hosted. I don't think there would be such a problem on a local SQL server. If you haven't stopped the sql service. These problems generally occur on remote mysql servers. I recommend that you run the SQL server on the same machine as the sphere server.
