[Nfd-dev] What makes nfd grow in size?

[John DeHart]

All:

I'm having a problem on one of the NDN Testbed nodes with nfd growing
to an unreasonable size.

There is a steady stream of Interests and Data going through it.
I have reduced the size of the CS down to 8K to see if that will
stop the growth but it doesn't seem to.

This is on the Tongji node. The virtual memory size of nfd will
continue to grow until eventually the node will get bogged
down and I have to restart nfd to clear things up.

I include below some ps samples that show the size and the change
in size at 5 second intervals.

What else besides the CS would cause nfd to continue to grow?

I should mention that I am experimenting with tcp faces to try
to alleviate some other network problems.


Thanks,
John
