Here what I noticed on freezing devices.
when I send STATUS# command it says below
Charging;GPRS:Link Down;NW Signal Level:strong;PPP_STATE:3;GPS:FIXED,SVS Used in fix:4,Signal:35,25,29,31,ACC:ON;Defense:OFF;
but when I connect the same device to another server It says GPRS link Up.
Let me also chip in, I am running 6.2 and I am facing the same issue. Device connect to server, they are online but timestamp (server time, fixtime, devicetime) remain frozen. There is no filtering. When I restart the server they all suddenly update to correct time and location. It happens randomly, but mainly affect gt06 protocol. If I downgrade to v5.8, no freezing. I thought it was a problem with my setup so I did downgrade to 5.8, but looks like there is a problem somewhere with v6.2.
Thank you so much for your response Maurice. I will try downgrading tonight.
I have a Lot of devices which use gt06 protocol. some of them are working fine. I noticed that the firmware of the working devices are different from others. i was thinking to flash the firmware also. Waiting for the technical support from the vendor. Here I mention the firmware I saw.
Working one: RDA_GO2H_ZKW_02_20230301
Freezed one: RDA_GO2H_HD_V02_20240111_10:15:21
sounds like the new firmware doesn’t support traccar.
If you think the problem is with 6.2, provide log samples for both to see the difference.
I downgraded the server to 5.8 and still I see the issue. device keep sending login packets and after lot of tries It started to send old locations as well.
My last option is to downgrade the firmware of the device. lets see.
@Harshana Srimal, Good morning, any results from your tests?
I contacted manufacturing company and they are troubleshooting the issue. will keep updating the thread.
When you have some time, could you please do a Mysql query to confirm that exactly the same thing is happening to you as it is to me?
Step 1:
SELECT deviceid, COUNT(*) AS count
FROM tc_events
WHERE eventTime > '2024-07-30 10:00:00'
AND type = 'deviceOffline'
GROUP BY deviceid
ORDER BY count DESC;
Step 2: Select the device IDs that have more than 20 Counts in less than 1 hour (the previous query).
Step 3: Confirm from the platform that it is indeed frozen.
after running below command
SELECT deviceid
FROM (
SELECT deviceid, COUNT(*) AS count
FROM tc_events
WHERE eventTime > NOW() - INTERVAL 1 HOUR
AND type = 'deviceOffline'
GROUP BY deviceid
) AS subquery
WHERE count > 20;
I found 1 device greater than 20 offline for last hour and as you said yes Its frozen. But this one is completely different from the issue that I focused. Anyhow I looked into the log file to identify the reason and what I noticed is

Here I notice that the device has sent the location. So I filtered by 2024-07-30 17:59:55 and I found that the position is filtered by invalid filters.

Seems like server misconfiguration. I use following filters in my config file. what about yours
<entry key='filter.enable'>true</entry>
<entry key='filter.invalid'>true</entry>
<entry key='filter.zero'>true</entry>
<entry key='coordinates.filter'>true</entry>
<entry key='coordinates.maxError'>5</entry>
After referring the log deeply, I found that the device disconnect the session before timeout. So I used the device on traccar demo server and the situation isn't changed. I feel that its a device fault.
Checking in my logs, no filter is activated, so my problem
It should be different from yours, my current configuration:
<entry key='filter.enable'>true</entry>
<entry key='filter.zero'>true</entry>
<entry key='filter.duplicate'>true</entry>
<entry key='filter.future'>86400</entry>
<entry key='filter.skipAttributes.enable'>true</entry>
<entry key='filter.skipAttributes'>alarm,ignition,result,status</entry>
<entry key='coordinates.filter'>true</entry>
<entry key='coordinates.minError'>20</entry>
if you can post your traccar log here, I can get much better idea. try to filter by IMEI and find out the last session. then filter by session.
Sure here it is:

what about your timeout settings? seems the sessions end after 1 minute and 58 seconds.
have you configured timeout in your config file?
You have to check jstack.
