Depends on how one defines unstable. My massive frustration was the spontaneous reloads, brought to a breaking point for me when the installation of AltUI brought it down to every few hours. Those reloads are gone in my no plug-in system. (I still get reloads in my 2nd Vera, which is an isolation ward for just two plug ins).
I have a system that runs reliably, events get triggered when they should, no hang ups. Yeah, I see CAN’s pop up in the log file, but I’m just not seeing big issues in functionality of my system that they are causing.
There certainly was a time when my log was full of nonce get floods, CAN’s, and hangups that paralyzed the mesh for 8-10 minutes. But not lately.
What is the Russian Roulette effect that you see in your system?
