Edge und Backend auf einem Rechner: Address already in use

obel1x · April 22, 2022, 6:31pm

Ich habe das Backend laufen auf Port
8081 für den Edge Websocket und
8082 für den UI Websocket

geht auch:

Apr 22 19:54:26 obel1x java[13328]: io.openems.common [io.openems.common.websocket.AbstractWebsocketServer] INFO : Starting [Edge.Websocket] websocket server [port=8081]

wenn ich nun den Edge auf dem gleichen Rechner ausführe und den “Controller Api Backend” an “ws://localhost:8081” anlege, gibt es viele Fehler:

Apr 22 20:06:05 obel1x java[13596]: 2022-04-22T20:06:05,462 [ae016bd)] INFO [onent.AbstractOpenemsComponent] [ctrlBackend0] Activate Controller.Api.Backend

Das sieht mit nicht richtig aus. Ich habe m.E. diesem nichts von Port 8082 mitgeteilt und ich weiss auch nicht, warum er versucht, einen “Server”- Port zu öffnen, anstelle sich nur zu verbinden.

Was mache ich falsch?

Hi @obel1x,

du solltest vorher sicherstellen, dass du dein Problem hier gelöst hast:
Authentifizierung mit FileMetadata - Deutsches Forum - OpenEMS Community

Eine fehlerhaftes JSON Dateiformat kann zu einem unkontrollierten Neustart der OSGi Komponenten im Backend führen.

Apr 22 20:06:05 obel1x java[13328]: 2022-04-22T20:06:05,650 [ector-58] ERROR [bsocket.server.WebSocketServer] Shutdown due to fatal error

Woraufhin dein Backend die Komponente neu starten möchte - aber die Ports noch nicht wieder frei sind:

Apr 22 20:06:05 obel1x java[13328]: 2022-04-22T20:06:05,740 [socket-0] ERROR [socket.AbstractWebsocketServer] Unable to Bind to port [8081]

Viel Erfolg!

also einen Fehler in der JSON kann ich so erst mal nicht sehen, bzw. wenn diese zum crash des backends führt: wie finde ich den Fehler? ich sehe keine logging- einträge über den crash beim shutdown und bind, kann ich da was einschalten für logging?

auch verwundert mich, dass ja zwei unterschiedliche komponenten den server starten: das Backend hat “io.openems.common.websocket.AbstractWebsocketServer” und der Fehler kommt vom “socket.AbstractWebsocketServer”
Sieht mir jetzt nicht nach einem Neustart des Servers aus, oder verwendet der zwei unterschiedliche klassen für die eine Verbindung?

obel1x · April 30, 2022, 9:50am

ok, jetzt habe ich das Format der json angepasst wie im anderen thread - und ja das sieht wirklich nach einem crash des backends aus, wenn ich mir die pids ansehe.

ich sehe aber nach wie vor keinen grund, weshalb das backend crasht und kein logeintrag, obwohl beide edge und backend- sockets im debug laufen. Ist hier ein Fehler im Programm?

ich füge nochmal die vollständigen Logs bei:
