can't store positions

Hi Anton,

How is this possible ?

2015-06-03 17:09:52 INFO: device: 6, time: Thu Jun 04 01:09:52 CEST 2015, lat: 47.xxxx, lon: 19.xxxx

6 rows in set (0.00 sec)

So as you can see, there is no device with ID=6. How is it possible ?

Thanks,
Mitya

Try to restart Traccar service and see if it fixes the problem.

well, I think that might solve the problem.. I just testing the stuff and I am curious about the reasons. Is this because you do have a cache ? If yes, how long does the server keeps it in the cache ?

Yes, there is a cache, but it should be cleared every 5 minutes.
