It's probably some sort of system routine. Look around in cron jobs, or something. You should google this, for all I know it could be related to OS automatically killing all long-term processes.

use google search

I can try clean folder /var/crash/ and reboot and it doesn’t help

How you know if problem is every 5 days at time 6:25 ?

it was the same 5 days ago and so on

Do you have logging traccar on ? If yes how big is log file ? Try to disable logging and reset tracar.

Did you check the limits?

Yes, I am always in the website, How can I see size log file and reset traccar?Thanks

Where are I check limits?

It really seems like it's your OS killing your process - considering it happens after exactly the same time it just seems like a routine task to kill all processes that are running for longer than 5 days. Could be some strange server configuration, or Traccar using too much resources.

I know it sounds stupid but if you won't be able to find a solution you could always make a cron job that restarts Traccar every 5 days at 6:26. Unless 1 minute downtime is not acceptable.

Maybe I can see something in config file xml server or traccar?

This did not happen before, everything worked 3-5 months normally and no one changed anything, and 2 months ago it started

1.restart traccar
sudo systemctl restart traccar.service

2.check logs, look for errors check size
/opt/traccar/logs

Logs is norm
