Actor crashed

I have random problem with crashed actors, because of unhandled exceptions.

...

after that daemon still works but not listening any more on the port, why supervisor doesn't restart actor?
If you want repeat problem, add rule on dns server :
iptables -I OUTPUT -d <client_ip> -j DROP
after that try to resolve ip address from client_ip through this DNS servers
