What is odd is that namestore (sending process) is at 100% CPU with 100k+ messages in the queue, while namecache (receiving process) is completely idle.

Maybe the issue is that namecache stopped processing messages?

This looks odd:

Note that the namecache process has /home/rexxnor/local/tmp/ for the unix path, while the namestore process has /tmp/gnunet-rexxnor-runtime/. So maybe the two are not even talking to each other at all?

Logic to add flow control was added in 722feeecccf0194b9912a5fff873be087fc65528
