The total mileage is reset to zero

And you didn't reset it?

Have you checked if the data was received in that order?

I have installed the application on several Android devices, there are no problems with other devices, only on this device zeroing can occur several times a day. Here are the logs on different days:

Reinstalled the application. While I'm watching.

Where can I see in what order the data is received?

You can check the server time.

The time on the server is accurate.

There is a possibility that the wrong time was set on the device. The driver says he changed the time. I checked the exact time now.

I'm not talking about your server clock. I'm talking about the server time from the positions.

The time corresponds.

Then the order is correct.

I will monitor the situation. I think it was because of the wrong time on the device.

It didn't work. There is still a problem. The distance is reset to zero. There is an error in the logs that I don't understand.

This error likely indicates that you removed an active device. Have you tried the common troubleshooting steps, like restarting the service?

I didn't delete the active device. The service was periodically restarted. Today I found the same problem on another Android device. Both devices were released last year. The rest of the old ones have no problems on them yet, they work perfectly.

I can't solve the problem. The total distance is still being reset.

I added this yesterday, but the problem is present.

Are you sure you're using the official version of Traccar without any code modifications?
