[SR-Users] Kamailio 5.2.3 segfaulting

[Daniel Greenwald]

This started happening after we enabled server certificate verification.
Datadog is showing a steady memory usage increase whereas previously it was
flatline. The changes we added were:

[server:default]
method = TLSv1.2
verify_certificate = yes
require_certificate = yes
private_key = /etc/kamailio/kamailio.key
certificate = /etc/kamailio/kamailio.crt
ca_list = /etc/kamailio/trusted_roots.crt

Previously we had client verification enabled but not server:

[client:default]
method = TLSv1.2
verify_certificate = yes
require_certificate = yes
ca_list = /etc/kamailio/trusted_roots.crt
private_key = /etc/kamailio/kamailio.key
certificate = /etc/kamailio/kamailio.crt
