Last night I disconnected power, waited and rebooted. Once again it came up but with “severe load,” so I rebooted again with a database rebuild. I watched the app and device load behave normally. They went down as time when by. But at some point, the problem reoccurred. Green LED, no response to the diagnostic tool, etc. I sent a note to the always reliable BobbyD. I also had marked this topic as solved, so I don’t get responses I will start a new one. I hope this is a hardware issue. Thanks.
What are your app stats and device stats logs saying?
If you have any custom apps / drivers that use TCP/IP connections (lan or wan) I would look at those. Check your logs for errors first and foremost Any reoccurring error or warn logs should be investigated.
It sounds like you have either an app/driver going nuts trying to connect to something or otherwise stuck in some sort of loop. OR possibly you have a device that is going bad (zigbee or zwave) and hammering the hub with endless messages until it crashes.
Thanks for the last two questions. When the hub successfully started, including after doing a full backup, it would sometimes start with severe load. However, assuming it stayed up for a while, the app stats and device stats both showed steadily decreasing load. I watched them drop into the low single digits and they were still dropping before I stopped watching. Unfortunately, the hub froze again anyway.
I have been in touch with support and they are investigating. Last night I tired a restart and the hub came up reporting a bad database. This was good as it also meant the diagnostic screen is finally working, so the tool set to address the issue just improved. I am waiting on further direction.
Thanks
Thanks, I will look into setting up a memory graph. Update: I got direction to do a soft reset and backup the database. Did so, but after booting the hub was not able to control z-wave devices. I watched the app stats and devices stats drop to normal levels. However, after a time the settings page would no longer respond. Shortly after that, the hub returned to being unresponsive, no diagnostics page, but responding to pings. Was asked for MAC address and provided it yesterday, waiting on next steps. Hopefully will get some good direction soon. I am guessing this is a weird one. Thanks all.
shutdown the hub, unplug power for 1 minute and power back up. See if that fixes. it
Sorry for the long time before an update. The hub itself was bad. I could get to the diagnostic page by pinging the hub repeatedly while it booted, but it would freeze again quickly. Got a new hub, did the restore and looks good. I am incredibly grateful for the z-wave backup capability. I have done the rebuild dance before and it is no fun!
Thanks for all the help, thanks to bobbyD for the resolution.
