Describe the bug

I run into this issue when my database gets reprovisioned while the Keycloak server is still running.

The DB becomes unreachable for 15-30 seconds, and then it should be fine again. I don't understand why this is happening, and it's making me hesitant to upgrade. I was previously using KC_CACHE_STACK: "kubernetes".

Couldn't this same state occur during normal operation—for example, if the DB is temporarily unreachable, or only one node can reach it, and so on?

If I stop the server and provision the DB, it works every time, and the JGROUPS_PING table appears to get cleaned up.

Maybe this is a very edge-case scenario and shouldn't be handled this way. I just want to confirm if it's 100% due to the moment when the DB connection becomes possible but the schema isn't fully there yet.

Shouldn`t it be self-healing?
