P1 readout to domoticz stops frequently after update

[Sl1mme01]

Hello
After update system is unstable and stops taking data from P1 meter
Have to restart, all data gone.
in log file :
2022-02-24 15:42:12.259 Status: P1 : WARNING: got new message but buffer still contains unprocessed data from previous message.
2022-02-27 15:24:49.274 Error: WebServer:8080 thread seems to have ended unexpectedly (last update 242.000000 seconds ago)

From what version to what version did you update?

Check the following instructions and hopefully you made backups.

Thanks for the response,
I had to reboot before ssh connection could be established.
Saved your proposal, today started Domoticz by "sudo services domoticz.sh restart"

I think you have to look at your current time on your RPi, see also https://www.domoticz.com/wiki/Troublesh ... _cold_boot

For Domoticz it is important to have the correct time. If it is far behind it will stop. So be sure you have the correct time set before Domoticz starts.

?

Those CRC errors come from a bad connection.
Could be cable, powersupply etc.
