I'm not sure if the same thing applies to the WMR200 but I know fine Offset devices lock up from time to time. some fixes are to either add Ferrite cores to the ends of the USB console cable, or to plug in a Powered USB Hub between the Rasbpi and your Weather Station Console. Also using a shielded USB cable can help too.
are you sharing the USB port on the Rasbpi with anything else?

thanks for your reply, there is nothing else connected to the pi only the station, the usb cable has ferrite cores on both ends, i will try an usb hub to see if it change something .

I had problems with the USBconnection between my WMR100 and the Raspberry3.
After I installed a powered hub between them last year, I have had no problems.

You'll always get lots of messages of that kind while reading data from this type of station because of the way MX reads the data; they are not indications of a problem and don't help with diagnosing the problem, unfortunately.

I don't have the same equipment, but here are some thoughts.
Can you tell if either the Pi or Weather Station is 'crashing' & rebooting? or do both stay running with failed data collection?
There are suggestions that adding USB hub helps some people. The hub should not do much except ensure that the weather station receives sufficient power all the time (certainly Fine Offset stations take power from the USB port [ie Raspberry Pi] once plugged in, rather than using their internal batteries. And Raspberry Pi's are known to need a sturdy power supply especially if you have powered devices attached to their USB hub. So make sure the Pi's PSU is a good one, especially if you are using a Pi3 or 2 rather than a Pi Zero W.
While on subject of power, have you checked that your weather station has good batteries?
And I see you live in France. Is it rural? Do you suffer the typical French momentary power glitches? You could try adding a USB power pack between the Pi's PSU and the Pi (to act as a UPS - uninterruptible power supply - power pack permanently on charge and available to power the Pi during any glitches).
At least those are the kinds of things I'd be checking up on ...

Hello, thanks for your help
1/ station and pi keep running but data are not send/received, i don't know
2/ the station is powered with adequate power supply and batteries are fine, usb hub is powered too.
3/ typical French momentary power glitches ?

I've been having a similar problem with increasing frequency. CumulusMX locks up and I get this error in the diagnostics file:

One other thing I should mention. When Cumulus hangs up and I get the error and I hit "Enter" to terminate the program, it will not restart. When I type in the commands, I get a "Cannot connect to station" error. I must reboot the system entirely to get it to work again. Not sure it's related, but it's a feature.

Did you attach the MXDiags folder to your post? Sorry but I don't see it.

No, I just posted the error text from the diagnostics. Here's the entire file. This is actually the diagnostic file from latest lockup from yesterday.
