[Freeswitch-users] FreeSWITCH not answering some REGISTERs

I use purely static config files for directory.
I upgraded to 1.6.15 and moved core-db to tmpfs, and interestingly, the issue is still there.
It  just happened in front of my eyes (I have a tail -F log/freeswitch.log | grep 'existing REGISTER’ running, and a tshark on port 5070 at the same time).
