Linux

My point to you before was, that it is likely that your RAM is NOT being gobbled up by this application. I don't mean you have a lot of "overall" RAM. I maean you have quite a bit available in a cached state that can be cleared to make way for applications. Unless you begin swapping pages out, this is caching and nothing to worry about. You SHOULD be using all the memory. That is what Linux does.

Unless this is a very poorly coded application or a JAVA application with poor garbage collection and heap size allocation you have little to worry about. What line in particular are you worried is a problem?

Tell me what lines in either free or the command I gave you are concerning you.

Memory leaks is indeed a bad thing and can be trick to find BUT if you used a tool like collectl it would certainly make things a lot easier. Similar in function to SAR but with much more comprehensive data collection and reporting. Since leaks can often be slow, you'd probably want to postprocess the data it collects rather than run it in real-time, so just turn it on and let it do its thing for awhile.

Then you can play back the data and examine the top users of memory by process! In fact if you do see your process using up real memory and that memory happens to be slabs, you can actually look at the top slab being consumed over time too! While the latter view is not by process, it can provide get hints to the problems since the slab names tend to tell you why that memory is being used.
