I have few mysql servers in replication master-salves in cloud service.
The problem is even thought all configuration, mysql versions, server's resources are the same, still I have inconsistency in slave's behavior.
For example, I have a set of stable mysql slaves which work perfectly, and a set of unstable slaves which still have seconds behind master even in idle mode, without traffic, and the set of unstable is always the same servers.
I am looking for something that is different in stable and unstable slaves. So far I didn't find something like this. Please, if you know how to find the thing that different share this with us.
