Any idea what's the equivalent error for aioredis so that both are fixed in parity?

No idea yet, I don't use async server :( It's unclear from the first glance and needs some investigation.

By the way - It's very upsetting when thread dies, and the rest of the application continues to live. I'd fix that - register a callback to call if thread stop, or crash the whole app (in flask-socketio case)

Hi @miguelgrinberg! I’m noticing an increase in the number of Redis connections (I’d expect a single connection per instance), and I suspect it might be related to this issue. I saw your commit - since RedisError isn’t necessarily a connection issue, it seems possible that new connections keep getting opened while the old ones remain active. Before I work on a fix, does it make sense to you?
