Hi Team

I have a 3-Node Percona XtraDB cluster. 1 Node updated automatically from version 8.0.34 to 8.0.35 due to which the cluster was broken. Other 2 nodes (running on 8.0.34) had an error saying that “Receiving request from higher version”.

Is the update automatic, also how can we avoid the upgrade in the production environment.

Hi, PXC does not update itself. Probably you have a cron job or something triggering a package update?
