Sikulix Freezing On Large Projects

Hello,
We are writing tests for a large project using sikulix. It helped us test many scenarios. But some of our tests are too long. At some point in these long tests, I think we reach the limits of the JVM and the test freezes. When we kill the sikulix.jar process, the test resumes from where it left off. At this point, I request your help. (I use thousands of images and static functions). I cannot detect the error. Can I manage the JVM where java -jar sikulix.jar -r path/test.sikuli is running or extra arguments that I can catch this error with?
