Hello, I have an issue with FreeRADIUS 4.0.x and Redis cluster. When I shut down one of the nodes (all have freeradius and use redis cluster), redis recovers and cluster state is OK but it seems freeradius doesn't refresh cluster topology, and when I send a packet to one of the working nodes it is trying to send command to node that is down and then just hangs and doesn't return response. I cannot stop radiusd after that (i.e. ctrl+c doesn't work) and it must be killed. The last line in log is this, and nothing is printed after that: Debug : (7) rediswho - [16] >>> Sending command(s) to 192.168.1.8:7004 (fr_redis_cluster_state_init) Btw. I changed the message in cluster.c just to confirm which function is called (there are two same Sending command(s) msg in that file), it is this line https://github.com/FreeRADIUS/freeradius-server/blob/master/src/lib/redis/cl... . So 192.168.1.8 is the node that I shut down to test high availability, and I send packet after redis is recovered. This doesn't happen when I shut down the other node, I can see in log how radius refreshes cluster topology and everything just continues to work. Before every test, I always make sure cluster state is ok and master/slaves are in balance on all nodes. Attached is a log file I get with `radiusd -X` on the node that fails and hangs after it tries to contact node that is down. Thanks, Milan
