Hi,<br>
<br>
I also recognized
this memory leak. In some cases the memory consumption of my
simulations increase linear over the time; at the end of the
simulation they consume up to 60GB. This problem especially arises
in
scenarios where Multicast is used as FW-Strategy and many packets
are
sent.<br>
<br>
I’m currently
working with ndnSIM-2.1 (Commit-Hash: a9d889b).<br>
<br>
Regards,<br>
Philipp Moll<br>

equal to X MB/s, so taking long time to finish would lead to
consume more!)

was working too fine. 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.<br>

</span>Can you clarify a bit (if you can share a simple
scenario that highlights the issue, it would be even
better). Was the memory consumption growing or got to a
point of high utilization and stabilized (you said it is
run-time, but then mentioned that simulation finished). The
reason I'm asking is that the old version of ndnSIM had
optimization of "virtual payloads", which is not available
in the new version. This has impact on the amounts of
memory used, but it should be just a constant factor
increase, not continuous increase during runtime.<br>
