I recommend searching because this has been discussed a countless number of times.

i already added the Java heap size and nothing is changing .

It has nothing to do with Java heap size.

So what is the problem?
please help !

Your database is locked. Again, this has been discussed many many times and if you search, you will easily find the solution.

Hey
i changed the locked attribute to false

update DATABASECHANGELOGLOCK set locked = false;

the server is started but i get 503 Service Unavailable in the ui

the application is restarting abnormal

I got this error

Dec 08 20:40:04 vps-fec626e1 systemd[1]: traccar.service: Failed with result 'watchdog'.

What is abnormal about it? If you want some help, you should provide details.

my server is restarting every 2 minutes there is this error in the log file

error - Connection refused - ConnectException (... < JsonGeocoder:126 < NotificationManager:99 < *:126 < BaseEventHandler:40 < ...)

and also this error in systemctl status

traccar.service: Failed with result 'watchdog'.

That error in the log has nothing to do with server restarting.

I got 503 Service Unavailable in the ui

That doesn't give us any useful information about the root cause. If you don't plan to provide more details, we won't be able to help.

I set web.disableHealthCheck to false and now it has been 10min without restarting
