[SR-Users] Kamailio stop responding to AWS R53 health check

[Andrew Chen]

So another update.  As it turns out, this remote IP sent a slew of tls
connections to the Kamailio box within the same second:

root at sjoprodkama51:/var/log # grep 104.248.215.53 falco_events.log | wc -l
114
root at sjoprodkama51:/var/log #

this all came in at 18:28:05 which matches the time of those errors.

Should this cause Kamailio to totally freeze up?
