traccar Service Stopped Automatically

[sankalpask]

Hi,
I have installed latest version of traccar mod in a windows server. Some time traccar service stopped automatically, so I have to re start the service manually. Is there any way to fix this?

Thanks.

You need to look into log files for error messages to find the reason of these stops.

[sankalpask]

traccar service automatically stopped on unknown time and I have started manually on 10.30 pm.
please check this log. thanks.

Your server is running out of memory:

FINEST|2476/0|Service traccar|17-12-10 17:08:42|java.lang.OutOfMemoryError: Java heap space

You need to allocate more memory to your service.

[sankalpask]

I'm only tracking 37 objects on this server. And using windows server with 3gb ram.
What's your suggested memory size?

[vitalidze]

You should figure our your current memory allocation to the java application. Probably it is calculated automatically. I would start from allocating 1GB. You can do it in the wrapper.conf file. Here is the config to add/update:

wrapper.java.maxmemory = 1024

(value is in megabytes)

Here is the note from documentation:

The maximal amount of memory in megabytes that the JVM should allocate. If -Xmx is defined using wrapper.java.additional property, then this property is ignored.

[sankalpask]

Thanks. I'll try this.
