Hi Andrew,

i have not an quick solution for that behaivour. I remember they are some changes to support openssl 1.1.1.

Normaly if the connection limit is exceed they are log-messages from kamailio for that.

Did you check max open files and limits, also the limit of kamailio itself on 
tls_max_connections
tcp_max_connections

see more on http://www.kamailio.org/wiki/cookbooks/5.2.x/core#tcp_max_connections

Maybe some graphs about your tcp connections are a good indicator to see trends that something wents wrong.

kamctl stats and kamcmd has some output.

Cheers

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

Hi Karsten,

Good point.  See below:

Kamailio ver: 5.2.5+bionic
Ubuntu version: 18.04.02 LTS
Kernel version: 4.15.0-1043-aws #45-Ubuntu SMP Mon Jun 24 14:07:03 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
openssl version: 1.1.1-1ubuntu2.1~18.04.4


Setup:
- R53 is our load balancer on top running health check on a pair of kams.
- First node has no issues and running the same setup + SIP traffic
- Second node as shown above was the one that went into "Unhealthy" state.

Hope this helps

Hi Andrew,

Would help if you could could describe your setup a bit more. 

Like the Kamailio version, the system distro and as we see many tls messages your openssl version. 

Maybe the traveling developers have any ideas then.

Hi all,


R53 reported healthcheck failure on tcp port 5060.  Looking at the system, all the ports that kamailio listens on can't be monitored remotely.  To test this theory, I can telnet successfully to consul port.  I ran tcpdump and see no responses returned back to R53 monitoring hosts:

Fixed the issue after restarting kamailio process.

Given this system is support production traffic, we have minimized the logging on it.  The events that we thought may lead to this is as follows:
