Hass process is being killed /defunct after a few hours (after 0.66 version)

Hello,

I have noticed that the hass process is killed after a few hours.

After that the web interface isn’t avaible anymore and could not be loaded.

The hass process is dead / defunct (zombie process) and needs to be killed with "kill -9 <pid>"

HA version 0.66 works fine without this isue. After 0.66 (0.66.1, 0.67) the process dies after a few hours.

What’s wrong here?

Any ideas?
