socket keepalive not working for azure redis cluster

[ZifanL]

I have a redis cluster hosted by azure. The client side is configured as follows with socket keepalive, but the connections still get closed after being idle for some time.

client = RedisCluster(
    startup_nodes=startup_nodes,
    password=password,
    ssl=ssl,
    decode_responses=True,
    skip_full_coverage_check=True,
    socket_connect_timeout=5,
    socket_timeout=3,
    socket_keepalive=True,
    socket_keepalive_options = {
        socket.TCP_KEEPIDLE: 300,
        socket.TCP_KEEPINTVL: 5,
        socket.TCP_KEEPCNT: 5
    }
)

Does anyone know what could be the possible reason or how to debug this? Thanks!

Hi! I double checked if it was an issue with SSL connections, but it looks like the socket configuration is applied correctly if you're using RedisCluster. It might be a server-side issue, connection might be closed by the server on memory usage overflow. Please follow this topic about client evictions and double check your cluster behaviour:

@ZifanL Feel free to reopen this issue if you find that it might be related to client
