Hi Vladimir,
This parameter can only cause the Full GC to kickoff more often but should not lead to OOM. Based on your settings, you have a max heap size of 4 GB. NewRatio=2 means that 1/3 of your Heap Size will be allocated for the YoungGen space, quite typical.
Regarding your problem I recommend the following:
- Enable verbose:GC so you can first identify the Java heap depletion pattern e.g. sudden depletion vs. capacity problem vs. memory leak.
You can read this article on how to analyze the verbose:gc output.
