Neuer ioBroker-Blog online: Monatsrückblick März/April 2026

[amg_666]

Hallo,

auch ich habe ein Problemchen seit einigen Wochen, dass der ioBroker nach einer gewissen Laufzeit nicht mehr über Browser erreichbar ist.
Wenn ich xxx.xxx.xxx.xxx::8081 eingebe kommt als Fehlermeldung Seite ist nicht erreichbar, bzw wenn die Seite noch offen war, dann dreht sich der bunte Kreis ewig und nichts passiert. Das System läuft manchmal 1-2 Stunden bis das auftritt, manchmal auch mehrere Tage...
Ich betreibe Raspberries im Master Slave Mode. Der Master hat aktuell node.js v8.11.4 und npm v6.4.0. Alle Adapter sind auf aktuellem Stand. Der Pi hat ein original Netzteil, Fehler der Speicherkarte schliesse ich aus, die hatte ich vorgestern getauscht, Fehlerbild bleibt bestehen.

Ich bin bzgl Raspberry und Linux eher Laie, für mich sieht der Log aber unauffällig aus (???)
Den Raspberry hatte ich heute rebootet und direkt danach mal $ ps auxww|grep io ausgeführt, auf dem "frischen" System sah es dann so aus:

Auf der VIS Oberfläche (Port 8082) läuft aber alles stabil und es werden auch Werte upgedated.
Hat hier jemand eine Idee woran es liegen könnte oder wie man hier am besten weiter vorgeht um das Problem zu identifizieren? Ich bin irgendwie mit meinem Latein am Ende...

Danke im Voraus
Andreas

Oops, habe grade gesehen, dass "divedancer" dasselbe Problem unter "admin läuft nicht durch" vor 3 Stunden gepostet hat, kann man die beiden Posts irgendwie zusammenschieben ???

setzt nen link hier zu dem anderen Beitrag..

aber zu deinem Problem.. hast du den backupit adapter laufen ?? der hat die Tage paar probleme verursacht..
ansonsten was sagt der LOG..

die Prozesse die du auflistet helfen relativ wenig.. hier ist der /opt/iobroker/log das richtige
