System disconnecting

smsoousa8 years ago

Hi, I have a problem with the system as follows, it simply disconnects by itself, having to restart the service so that it returns to normal, the first time I imagined it to be the server, then I changed the server and the problem persists, The installation and configuration of the system is standard. Could you tell me what might be happening? Or is there any way to create a cron so that when the service stops it automatically comes back?

  1. What are the hardware specs of your server?
    2. 

  2. Do you have any other services there?
    3. 

  3. How many user and devices do you have?
    4.

  1. This is the hardware configuration:
    2. 



512MB Memory
1 Core Processor
20GB SSD Disk
1TB Transfer


    

  1. No, only the traction service.
    

    2. 

  2. I have no user or device yet, the system is newly installed, today when I went to access it was already off the air.
    

    3.

You need at least 1GB to run Traccar without issues. It might be possible to run it on 512MB, but it would require some optimizations.


smsoousa8 years ago
The first server had the following settings:


CPU 2 Cores
RAM 2048 MB
Disk space 80 GB
Bandwidth 2000 GB


And yet the service stops unexpectedly, so I can first conclude that the problem is not in the hardware configuration.


Anton Tananaev8 years ago
Is error the same on 2GB server? I can take a look if you provide access.


smsoousa8 years ago
I sent the access to your email

Same problem here. Did you find any solution?
