Redis redis always connecting to itself.

Describe the bug

I create redis cluster in kubenetes. 3 nodes 6 redis-server , every node 2 redis-server (one is redis-master ,other is redis-slave)。 If i restart pod, redis-master and redis-slave exchange ip, then redis-slave will reconnecting to itself.

It wasn't clear to me what's going on in your log, it would be more helpful if you've provided CLUSTER NODES output before/after you bounce the cluster.
