Answer 1

If you are sure there are no memory leaks in your program, try to:

1. Increase the heap size, for example -Xmx1g.
2. Enable the concurrent low pause collector -XX:+UseConcMarkSweepGC.
3. Reuse existing objects when possible to save some memory.

If necessary, the limit check can be disabled by adding the option -XX:-UseGCOverheadLimit to the command line.
