OutOfMemoryError

Hi! Sometimes, I have this error on one of my instance. What I do wrong?) Can I increase Java heap space?

Refer : https://www.traccar.org/optimization/

can I configure it in docker?

Yes, you can. The relevant part is the memory limit.

can you tell how it configure in docker compose? I can't find information

You have to add the -Xmx parameter to the command line. Not sure how to do it in docker compose specifically, but it should be possible.

happened. need to add a section in docker compose:

    entrypoint:
    - java
    - -Xms2g
    - -Xmx4g
    - -Djava.net.preferIPv4Stack=true
    - -jar
    - tracker-server.jar
    - conf/traccar.xml

and how about

WARN: Error loading timezone aliases: inStream parameter is null

don't understand this warning

You can probably ignore it.
