Verbindung zu signald #70

Closed eknoes closed 3 years ago

Manchmal gibt es Fehler beim Signalbot mit der Socket-Verbindung zu signald.

Wir nutzen semaphore als Framework, das verbindet sich mit einem Socket von signald. Dabei kommt es manchmal zu Fehlern, die ich bisher nur eingeschränkt nachvollziehen kann, bspw.:

Meistens startet sich dann unser Bot neu, manchmal funktioniert dann alles, manchmal laufen auch beide Services aber unser Bot ist nicht wirklich subscribed. Ich vermute, wir machen irgendwo was mit dem Socket öffnen / Schließen falsch, möglicherweise auch in semaphore.

Scheint nicht mehr wirklich aufzutreten.
