Hello all
I am using the latest version of Traccar on a Oracle Free Tier Ubuntu Server, and I have only 1 GPS tracker.
Previously I had a ST-901 4G, which worked good, but would consistently send records whilst ignoring it's own config. However the server was able to cope with that fine. I removed the tracker for a period of time whilst I intended to replace it
Now I have a FMC920, but I was very overwhelmed by the setup possibilities. I have it currently set to 5 sec record and send records whilst moving, and 2 mins record and send records whilst stopped. It's also set to AKL so every time it sends data, the server responds with the OK.
My issue is that as time goes on in the day, it creates a very bad delay but I'm struggling to understand why.
After a day here's an example of what I have in the logs:
2026-08-27 23:16:50 INFO: [T47ef503b: teltonika < 92.40.188.41] 00000000000000588e01000001a04582fb1800000000000000000a00a001101000000000000c000500ef0000f00000150400c800004501000500b5000a00b60007004230a500430fef00440000000200f100005b7c001000041bc900000000010000164e

The first line shows that the Tracker is actually sending correct data at the correct time, but shortly after the server logs is adding records from 11 hours ago? Those data entries of 23:17 would have been sent from the tracker to the server at 12:11 etc, but the server doesn't seem to acknowledge them till then.
The result of this is the map showing completely out of date location data, and you often see it moves as it slowly updates those entries. But my confusion is whether those delayed lines are coming from the tracker, or if that's the server adding them to the database after massive delay.
After a server reset it returns to normal, so far I've left the car off for a day (so it sends data every 2 mins) and it seems to be coping well after a day. But it's whilst it's moving that something doesn't seem to be able to cope, and creates a longer and longer delay.
