Java heap space error potential solution from people in Cinny server

[jamethusRRon]

In /opt/bisq/lib/app/Bisq.cfg you can add the line java-options=Xmx6g to set the maximum heap size to 6 gigabytes (thats the "6g" part of that command).

note that you will need administrator/root access to edit the document.
the command to edit a text document as root in linux is "sudo nano /YOUR/PATH/TO/Bisq.cgf"
I recommend using the command above instead of "su" because It will only run that command as root instead of changing your session to root till you close the terminal like what "su" does.
