Traccar Device Freezing issue
Don't see any issue here. What about OsmAnd?
I see a lot of these 'Cache add device' 'Cache remove device' lines, but I don't see any device freeze yet.
All the devices (but one) are also pretty stationary at the moment, so that could also explain why everything is still working :-)
Tomorrow morning I'll make another trip and hopefully we get useful information out of that.
Sooner than expected: at 18:20 a device using the h02 protocol froze with error - Cannot invoke "org.traccar.model.Device.getUniqueId()" because "device" is null in the log.

2024-08-07 18:20:41 INFO: [T9982b8bc] connectedThe device using the osmand protocol froze as well, but after a traccar server restart, it uploaded the missing data.
This is very helpful. Looks like we have some race condition. I will investigate more.
Thanks in advance. Let me know if you need more logging or want to test more.
(Next week will be a bit difficult, I'll have limited access to my Traccar server.)
Please try this updated version:
Preliminary verdict: this version works better, no errors in the log yet.
Gathered as many devices I could find and made a trip. All devices are still alive and nicely report their position.
I'll keep this version running the rest of the day, see what happens.
We had the same problem, we run the API to receive only readings and if the back server is working in a timely manner, strangely it does not update in the web interface 6.3 they freeze after a certain time, the browser history is deleted and it works again, for a few minutes, in the “log” file it does not show any connection or new data, when it freezes but in the BACKEND SERVER the data arrives without problem, whatever the report time, in version 6.2 in some models it does the same... not in all!!
Still no device froze, but there is still a minor issue:
In this case (only seen once) it seems that the device is removed from the cache just before the getCalendarId is invoked.
But as I said, it is not fatal and doesn't freeze devices ... yet

Hello have installed the preview, but I am still having the same problem. The difference is that in my case, the devices suddenly went offline and do not reconnect even after restarting the server. This happened when I updated to version 6.3. However, if I point the device to the Traccar demo, it connects immediately. I am sharing a portion of the log where the error 'cannot invoke' is still observed."

2024-08-08 08:58:13 INFO: [T2ec98895] disconnectedC5roki thanks for checking. Here's another iteration that should hopefully fix all remaining issues: https://www.traccar.org/preview/.
AvlMexico, this doesn't seem like the same problem as we're discussing here, so I recommend starting a new thread if you want to discuss you issue. Obviously you need to provide all the relevant details, like logs.
tecseguridad, your issue is completely different. It indicates that you have a corrupted database with link to objects that don't exist. You have to fix this in the database.
Tested the latest preview, but just after the start it gave WARN: Failed to add device cache - ConcurrentModificationException that actually caused one of the devices using the h02 protocol to freeze. I had to restart the server to get a location update on the frozen device.

Log has a lot of cache logs like this one:
I guess that the 'Exception' part in the Cache logs is to force the logging?
