If you the target of a stream, do you need to restart NPM?

[csm10495]

I have a mysql server container running downstream of NPM. I'm forwarding port 3306 on udp/tcp from NPM -> mysql:3306.

It seems like sometimes if I restart the mysql container, the stream stops working. Sort of like the ip address or something underneath changes and NPM doesn't notice it. I think if I restart NPM the issue goes away afterwards.

Is this expected behavior? .. I don't think the same thing happens with regular proxy hosts.

To work-around, I've hardcoded an ipv4 address for my mysql container, and that seems to keep it consistent so that the stream doesn't stop working when mysql restarts.
