I have one Chirpstack instalattion in use. Sometimes the application-server stop working (API and Web Interface is not accessible). The only solution is kill chirpstack-application-server process and restart service.
On journalctl -u application-server:
Jul 12 06:52:07 chirpstack-application-server: 2021/07/12 06:52:07 http: Accept error: accept tcp [::]:8080: accept4: too many open files; retrying in 1s
Any solution fot that?
