subscription to redis channel does not keep alive

Question

I have one client subscribe to one channel. After a certain period of time about 10 minutes idle, the client can not receive any message, but the publish command still returns 1. I've tried redis-py and servicestack.redis clients. The only difference is seems the idle period can be little longer when use servicestack.redis.

Any idea? Thanks in advance.

Answer 1

I had similar issues with an older version of Redis that was fixed by the latest version.

As an alternative you could try adding a separate thread that sends a "PING" command once in a while to keep the connection up.
