Zwave error. What does this mean?

Since a few days, frequently my Zwave devices show off-line and generally they come back after a restart.
This is what my log shows:

Anyone has an idea what needs to be done ?
Thanks

Googling this error, it could indicate that a connection was trying to be used even though it had already been closed. What kind of Z-wave adapter setup are you using? If it is a directly-connected (USB) adapter, many recommend using the /dev/serial/by-id/ path instead of the /dev/tty path for more reliable connections. If it a serial-over-IP adapter, there could be any number of network issues/delays causing the connection to be closed. Next steps would be to save detailed logs from Z-Wave JS UI to capture exactly what it is failing to do and hopefully why.

Thanks. I will look at the Z-Wave JS UI. I am using a Zooz 800 USB stick.
