What version are you using?

You should upgrade first.

By the way, why do you have so many server instances?

jamel2 years ago

Jamel, CPU load seems too high.. My cpu usage in a monocore is mostly 0.00... (it increased as I started ssh session)

It is not normal to have multiple instances of the service.

Hey Richard,
yes i know this is weird the pid is using 32% of the cpu .

OK. Weird that it shows different PID for each though. That what confused me.

Hey
is it normal that my traccar server uses a lot of cache memory ?

0.7 the main pid.... 0.0 the rest.
You have a serious issue..... ¿how often (what freq.) your devices report location?
