That particular image has been problem free for me on unraid for I dunno feels like years now. They did do some update that I missed the notes on that wiped out my database and I had to re add everything. Wasn't too happy about that.
But every couple of days, the logs start to fill up with random java exceptions, then it starts leaking memory and eventually brings the host to a grinding halt and crashes.
I've had no troubles when using the Cloud Key Gen2 Plus, but I like the idea of the controller NOT being located on site.
