In crome when this happens websocket fails then /api/devices and /api/positions fails then the browser just reloads its,but in firefox it goes further with get /api/session failing causing the browser to logout,please someone help

You need to figure out why it restarts.

i am on ubuntu 18.04 ram 2gb,mysql 5.7.4, i have unintsalled Traccar version 4.10 and installed version 4.8 and it works fine,i have not yet figured out what is the cause for it to happenn,and oh i said every five seconds but its every five minutes...

Could be something related to systemd watchdog. Check logs.
