We're currently piloting Mailman3 to replace a failing Ecartis installation. We've had to push back our go live date several times due to stability issues with our Mailman 3 installation. We currently have Mailman core 3.2.0 running on Red Hat Enterprise Linux 7.5 with 2 vCPUs, 8GB RAM and 25GB swap space. Occasionally, we see mailman become unresponsive both via the REST API and the web UI. We haven't seen anything glaring in the logs but would be happy to check further. I know Mailman 3 powers many large lists and would appreciate any performance, stability and tuning information that can be provided.

When it is unresponsive what is the state of the 'rest' runner and is it listening on localhost:8001?
What do you do to 'fix' it?

I believe it's still listening on localhost:8001. I'll add some additional checks to our monitoring system to help us track down process crashes.

To "fix" it, we restart mailman core with our systemd service script.
