Please help me at earliest

I have also change in wrapper.conf.default file and try to increase memory

wrapper.java.initmemory

wrapper.java.initmemory.relative

wrapper.java.maxmemory.relative

wrapper.java.maxmemory

I restarted the server and then restarted the traccar service but same problem persist.

According to the logs, it's working just fine.
