Problems migrating from 5 -> 6.12 RPi3 ARM
Is your system 32 or 64 bits?
Soorry for the delay: that's AARCH64 (uname -m)
Did I download the wrong Architecture?
Sounds correct. Have you tried searching the forum for other similar issues?
Yes I did.
Some had to do with architecture. Some with XML formatting probably. Some with Java. Seldom the same service messages or if so with description or logs. But no logs here.
Afaik I had some Java issues on this machine .
Probably this has to do with the power saving settings. I research and get back here...
Checked Voltage settings again today, Back to all standard settings (freq and voltage) did not solve the issue...
almost forgot: used ufw firewall, which I disabled.
But that should not have to do with the traccar service restarting ...
One thing to try - use a standard Java that comes with the system.
Hey.
Thanks... currently trying to reinstall standard JDK (open jdk 17). Before that I tried to grade to version 6.8.1 but system still keeps restarting traccar. Powersettings back to normal freq and volt settings.
Running this jdk now:@raspberrypi:~ $ java -versionopenjdk version "17.0.18" 2026-01-20OpenJDK Runtime Environment (build 17.0.18+8-Debian-1deb12u1)OpenJDK 64-Bit Server VM (build 17.0.18+8-Debian-1deb12u1, mixed mode, sharing)
no success unfortunately. A pity that ist went this bad, traccar war really running ok before with no issues... Guess this will be a clean install...
...really strange. I wiped the SD Card and startet fresh with RPI Trixie lite 64 and traccar 6.12.2.
Still the traccar installation is restarting itself.
minimal traccar.xml is correct? see below
<properties>
<!-- Documentation: https://www.traccar.org/configuration-file/ -->
<entry key='database.driver'>org.h2.Driver</entry>
<entry key='database.url'>jdbc:h2:./data/database</entry>
<entry key='database.user'>sa</entry>
<entry key='database.password' />
</properties>
It's not a valid XML. Where's the header?
Sorry, i post it as plain text:
This is sudo nano /opt/traccar/conf/traccar.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE properties SYSTEM 'http://java.sun.com/dtd/properties.dtd'>
<properties>

</properties>
in case somebody is interested:
I went along this: https://www.traccar.org/forums/topic/traccar-server-680-service-failed-to-start/page/5/
in the end with no success for 6.12.2. and also 6.8 I reverted back to arm64 5.12, which seems to run stable.
On the RPI3B+ I installed Trixie lite (headless). Would it make sense to also go back to bookworm and try Java updates and 6.12.2? Or try a non-headless RPI OS?
Unfortunately with mentioned OS and various Java trials I couldn't make traccar run.
So be it the older traccar version...
if anybody is interested:

Hi,
After upgrading from 5 -> 6.12 in RPI3B+ traccar keeps itself in a loop of failing service starts.
Had traccar 5 server running on RPI3B+, Raspian Bookworm, with Caddy to support HTTPS, RPI Config optimized for power saving incl. underclock and volt. H2 Database, 2 devices. Basically no issues with 5, except notification issue: email config/Notification had no test button --> wanted to try upgrade.
Followed instructions here: https://www.traccar.org/upgrading-traccar/
unfortunately backing up both database and config xml file to a folder that got deleted during uninstall, config and DB are lost - not so much of an issues - all test related so far - but annot compare old XML config files anymore.
When Installing 6.12 all went along smoothly, no errors.
Problem now: traccar service doesn't start correctly, no log is written to traccar/logs.
Thought undervoltage/clock would be a problem so at least lifted voltage back up.
Too, some forum entries pointed to JRE/JDK and XML format issues with installation.
So uninstalled - updated to JDK 17 - reinstalled 6.12.
Also made sure traccar.xml is default.
Problem remained.
Can't make sense of the restarts here - is Java the issue:
My traccar.xml contains nothing but standard installation entries:
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE properties SYSTEM 'http://java.sun.com/dtd/properties.dtd'> <properties> <!-- Documentation: https://www.traccar.org/configuration-file/ --> <entry key='database.driver'>org.h2.Driver</entry> <entry key='database.url'>jdbc:h2:./data/database</entry> <entry key='database.user'>sa</entry> <entry key='database.password' /> </properties>Any Help welcome
