Traccar 5.9 restarts several times during the day.

I'm seriously considering making a backup and restoring the VPS.

I thought why dont you make a backup of traccar server and the mysql database and then restore it on another vps to root out if the issue is with the OS or with traccar itself.

Antonio Juniora year ago

Yes, I think I will do it, but the difficult part is changing the devices to the new IP, of course those that are not via the domain. but thanks for the information.

I am missing some context about your issue. Did you already use this server for a longer with traccar 5.9 ? Was it running without issues before?

When did the problem actually occure, after updates of the OS, after changes to traccar server, without any changes?

P.s. you could just restore traccar server to another vps for the devices that use an url (to test it). Or you could add the devices to a group in your current server and use Group command to change the server ip.

This server has been running for 4 weeks and has already been deployed with traccar 5.9. I've been using the VPS for some time and never had any problems, I think something may have failed in the update before installing traccar. Great suggestion from you to relocate devices. "you can simply restore the traccar server to another vps for the devices using a URL (to test it). Or you can add the devices to a group on your current server and use the Group command to change the server IP. " Perfect, thanks!

@Track-trace @Anton
Greetings gentlemen, I carried out some tests simulating 250 devices connecting to traccar 5.9 every 10, 9, 8, 7, 6 and 5 seconds. When we have less than 8 seconds I receive two responses from the API as follows: This gets worse when I have the frontend logged in to an account with admin access, I did the test logged in with admin in more than 1 browser and it gets considerably worse. Ah, in relation to Memory and CPU, there was no spike at any point. 6GB RAM and 4CPU. Could you suggest something to work around please?

It seems like you're using wrong port for devices.

Antonio Juniora year ago

@Anton I simulated with osmand protocol sending to 8082 because API recognizing protocol redirects to correct port? I captured the request through the traccar client app.

Anton Tananaeva year ago

It proxies requests, but you shouldn't be using it. It adds unnecessary overhead. It was added because too many clueless people trying to use web port for devices.

Antonio Juniora year ago

I understand, so should I simulate a specific one, such as 5023? because I don't know what else to do with this server having a problem. I didn't find anything that would cause traccar to reset. would it be the server bandwidth?

Anton Tananaeva year ago

I only pointed out that you should use the correct port. Port for osmand protocol is 5055, not 8082, as you can see from the documentation. You should start by using the correct port.

Antonio Juniora year ago

Ah you are correct Anton, sorry for the confusion.

Track-tracea year ago

And let us know the results when doing the same test on port 5055 Antonio
