QNAP starts but crash out

[Yazsan55]

Minimserver kept crashing, so I uninstalled it and reinstalled. I have the following error report in minimserver-out.log file. This is the last part of it. Where can I fix this, i.e. increasing heap size?

I am looking at package on minimwatch, it says minimserver-update-250.
