Stack traces look fine. I guess you should look at which thread is actually using 99% CPU time. You can use Process Explorer for that:

I have traccar-server 3.7 running on windows 7, with only one phone with tracar-client for android for testing. This is the second time (in two weeks) the task manager shows traccar-server taking 99% of cpu... What could be the cause ? Network problem ?
