First of all, why did you install an old version?
As for the problem, it usually happens when you use MySQL with MyISAM engine. If that's the case, you should re-create database with InnoDB engine.
My apologies, the traccar version we installed is 3.8. Below we are getting following logs in "/opt/traccar/logs" file.

Now can you please help me out or changing the database engine is the only solution, then if i need to change database engine please provide some links to do so.
Thanks for your valued time Anton.
You can change the engine type, but the problem is that because constraints are missing, you won't get them even after the change.
I guess the easiest way is to create a new database, let Traccar initialise the schema, and then copy over all the data.
Hi,
