I traced the issue to lib/serve.js#L15. It works fine if I disable that line that emits the SIGUSR1 signal when restarting.
Also, I was able to fix the restarting behavior in my application by placing this in my server/index.js file:
process.on('SIGUSR2', () => {});However, I could not fix custom-server-micro in the same way. With the "fix", rather than crashing on restart it restarts once and then is hung. It's strange, considering I used that example as a reference for using micro/micro-dev with next.js in my app. My app has more going on now, not sure why difference... I'm running these inside a docker container.
Some more info from running it with npm vs yarn:

From the log I notice I'm using node v8.11.4 which seems old... but that was by intention to match the version I have on target devices (Raspberry Pi). I can look into options to upgrade that and see if it has something to do with this issue.
Update: using node v10.13.0, similar behavior although it seems to take longer to restart.
