Piyush Verma6 years ago

Hello Friends,

I was running traccar server since long time and all was running well.
Then suddenly it stop working, when I diagnose then found storage is full, then I make free space and restart traccar.
It start working back but stop after an hour,
every time I restart it stop working after as hour,
How ever gps devices are pushing data continuously I can see from log.

Any suggestion what could be issue ?

In Logs I can see out of memory error, 

cat conf/wrapper.conf 
wrapper.java.maxmemory = 1024

in wrapper.conf file I have added maxmemory but still same

What's the question? Clearly you don't have enough memory.

Hi Anton,
Thanks for your attention.
Is conf/wrapper.conf right place to make entry ?
Only one line entry "wrapper.java.maxmemory = 1024" is enough to increase memory ?

I think 1024MB setting did not take effect.
How much is ideal memory for trackcar with 100 devices?

Memory requirements depend on your usage, not just the number of devices.
