So, das ist schon mal schief gegangen.
Irgendwann gab es keine Ausgaben mehr in gdb (war eingefroren), keine Prompt und keine Möglichkeit mehr, die nötigen Befehle einzugeben, die Logdatei schreiben zu lassen.
Angeblich lief der Symcon Service noch, es gab jedoch keine Möglichkeit mehr darauf zuzugreifen (weder IPS-View noch IPS Konsole).
Einzige Möglichkeit war, GDB zu killen. Danach lief auch der Symcon Service nicht mehr und nach und nach stiegen dann auch debmatic und der SSH Zugriff aus.
Ich musste den RPI ganz vom Strom trennen und neu starten und probiere das Ganze noch mal neu.
Kurz vor dem Crash hat übrigens das Connect Modul von Symcon begonnen, Meldungen zu produzieren:
