I have noticed the following issue which began with builds somewhere between
git master commits bff0a08 and 6173ef7. I did not see this issue with my
previous builds and haven't been able to pin down the problem, which is why I
haven't formally filed a bug.
Any help or guidance is appreciated, because this has crippled my use of
Kamailio. Only a restart enables it to work again until the issue recurs.
ERROR: tls [tls_server.c:189]: tls_complete_init(): tls: ssl bug #1491

I currently build against and run openssl-1.0.1k-12.fc22.x86_64.
I have a very small operation and the only change on the operational side is
that all 5 of my mobile UACs (yes, that's all) have switched from
CSipSimple/Android to Zoiper/Android, which doesn't yet have support for
client-side certificates so verify_certificate and require_certificate are off
for both the server and client config.
The server is started with:
/usr/sbin/kamailio -P /run/kamailio/kamailio.pid -m 64 -M 8
I have tried modifying the shared mem to 128 but the issue still occurs.
Even right now, I am seeing the error when only one UAC has established a TLS
connection:
# kamcmd tls.list
