Struggling with new server - keeps stopping
Looks like your server has timed out. Usually it indicates lack of resources.
Thank you.
Is there a way to extend the timeout period?
Anything I can do to fix these errors:
INFO: lib not found: /opt/traccar/lib/extended/glazedlists/glazedlists-1.8.0_java15.jar
INFO: lib not found: /opt/traccar/lib/extended/glazedlists/commons-beanutils-1.8.2.jar
INFO: lib not found: /opt/traccar/lib/extended/glazedlists/commons-beanutils-1.8.2.jar
INFO: lib not found: /opt/traccar/lib/extended/glazedlists/glazedlists-1.8.0_java15.jar
You can extend timeout in wrapper config, but I don't think it would solve the problem.
As for the "lib not found" logs, you can safely ignore them.
Thank you Anton, I will dedicate a RPi 3 for the job. Do you think that will be adequate for the task?
You need at least 1GB of RAM.
How about 2GB RAM server, with "wrapper.java.maxmemory=768" still shutting down ? Same error "clock heap, starvation....... " Google Geocode requests between daily limits (1.400). centos 6 vps, great bandwith and resources. Testing server with only two devices, the server shuts down around 20 or 24 hours working....

I think it's safe to ignore, those 4 "lib not found" warnings...
Are you sure you don't have anything else on that server?
Like What, I use it like an OpenVPN Server, do you mean that ?
I mean how much free resources do you have on the server.
[root@gf1 ~]# free -m
total used free shared buffers cached
Mem: 2048 295 1752 3 0 27
-/+ buffers/cache: 267 1780
Swap: 2048 252 1795
Then the issue must be somewhere else. You can try to run Traccar manually without service wrapper and see if solves the problem.
How to achieve that ?

I have recently installed Traccar to test a TK206 device. It works well when it works, but I find that it fails on a regular basis, without any clear reason. I am running on an Ubuntu VM, 6 core i7, 6GB ram.
In the logs I see this:
and in the wrapper log I see:
I also see the following on start-up:
Any support will be appreciated
