[SR-Users] Kamailio stops processing requests mid script

Hello,
if the traffic is over UDP, the Kamailio workers were blocked in
recvfrom(), meaning that nothing is passed from the network layer to
them. If you see UDP packets coming to Kamailio via ngrep/sngrep/...,
then is the OS that drops them via firewall or some other app that
controls the network traffic.
Cheers,
Daniel
