Facing api issue

here is

root@New-Server:/home/ubuntu# cat /proc/$(pidof java)/limits | grep "open files"
Max open files            524288               524288               files     
root@New-Server:/home/ubuntu# 

I guess I have no other ideas, but you really need to figure out why those connections are reset. That's not something that we do, so it's probably the OS.

Hi im trying to learn from these issues also. Could you try this an let me know if it makes any difference.

1. Disable all protocol ports in /conf/default.xml that you do not use.
2. Then Restart traccar server and allocate 2G for it:
   java -Xmx2G -jar tracker-server.jar conf/traccar.xml &

@Shivam

as Anton has pointed out earlier, you are having issues with resources.
check your disk space using "df -h" from your terminal and lookout for /dev/vda1 it would most likely be above 80%

clean out your position table to have more space, and carry out the optimization has from other suggestion above.

Please let me know if it works for you.

i Was also facing the same issue and tried these steps but all the devices are getting offline, after executing this command:

You have a port conflict, as the error clearly states.
