Can no longer control devices - Any help urgently received!

[akirkby]

Today my HS3 ZEE S2 has stopped controlling most of the devices connected to it, I have tried a restart but am seeing some worrying messages in the logs on startup -

Z-Wave Error

Error, Exception in GetZWNetworkS: database disk image is malformed database disk image is malformed

Z-Wave Error

HomeSeer UZB: The HomeSeer UZB interface did not respond to the request for the controller capabilities - it may be disconnected or malfunctioning (3).

When I try and control some of the devices on the network, there is a flicker of activity on the UZB interface but nothing is controlled. When I check in the log file it appears it the device was controlled but nothing happens.

It appears you have at least three seemingly unrelated errors (1) a Z-Wave database corruption, (2) a misbehaving UZB controller, and (3) an out-of-memory error on the command that is attempting to read the Linux OS version:

Linux version: ApplicationName='./run_command_raw.sh', CommandLine=''uname -a'', CurrentDirectory='', Native error= [COLOR=#c0392b][B]Out of memory[/B][/COLOR]

First thing I'd recommend checking, even if just to rule it out, is if you've managed to fill up your SD card. This could result, for example, from having enabled a verbose logging option and left it on for too long.

You'll need to get yourself logged into the Linux command line. (the 'Linux Tools' option will be prone to the same failure that the "uname -a" command suffered). Either connect a monitor & keyboard or remote in via ssh.

Once logged in, run

df -h /

This should return something like

Filesystem Size Used Avail Use% Mounted on
/dev/root   15G 6.6G  7.1G  [COLOR=#c0392b]49%[/COLOR] /

If "Use%" is 100%, you've filled up the SD card and will need to deal with that first.

Hi - the issue was down to Z-Wave database corruption. 'Reset Z-Wave Data' and then restarting sorted this out.
