we have some clues that under some certain circumstances, there might be something wrong going on with the memory consumption.

However, it is not clear to us yet why this is happening. We speculate that this has to do with NFD itself and the way it maintains and deletes its data structures (specifically, PIT and CS).

I can get back to you with more details as soon as we are done with our investigation.

Now I'm using the latest version, I changed the old application to work over the new ndnSIM and noticed huge memory leaks that are proportional to the run-time; On some computer it took more time and consumed 10 GB of RAM !! and on another faster one, it took less, hence consumed less RAM (4 GB or less), both are still huge amounts of memory as I'm using a small topology with 18 nodes and an average frequency of 500 requests/s; and all of that was running fine on the older version of ndnSIM.
