Yes.  So, we never faced this situation in our preproduction environment and only seen when we enabled this version on our beta production.  The question really is how did this get kamailio stuck?   I've seen this error even on 4.1.5 but not at 100+ msg / sec entry rate.

We will enable TLSv1.2+. and see if this would go away.

Hello,

the next error that you had it is typically happening when the version of TLS is not supported:

Nov 13 18:28:05 sjoprodkama51 /usr/sbin/kamailio[20304]: ERROR: tls [tls_util.h:42]: tls_err_ret(): TLS accept:error:14209102:SSL routines:tls_early_post_process_client_hello:unsupported protocol

You force TLSv1.2, but maybe the checks are done with other protocol. Can you try with method = TLSv1.2+ or method = TLSv1.1+ ?

If you get in the same situation, do not restart until you grab the 'kamctl trap'.

One more question: did it work for a while and then suddenly it started to throw those errors?

Cheers,
Daniel

Hi Daniel and all,

Any suggestions on what would cause this?

Btw, one of my colleagues googled up a similar issue and seems to point to the siptrace module??

Hi Daniel,

So first of all, R53 won't route anything over to this node as it marked as "Unhealthy", which was the first indication there was something wrong with this node.  It sends ping probes to tcp port 5060, which we saw was listening on the Kamailio device.  Then we used other methods to test the connection such as "telnet <IP> 5060" which usually should connect but it didn't.  We ran this both locally and remotely which generated the same result.  I even ran tcpdump to see what is happening.  All I saw was R53 ping messages come in, but no response going back out.  So I restarted the Kamailio process and that fixed everything.

The TLS method used is TLS1.2:

method = TLSv1.2

Hello,

first to clarify it: the fix for libssl referred as being in 5.3.0 is also in 5.2.5, with a slightly different approach (some code is directly in tls module in 5.2.5, while in 5.3 has been added to the core), but same overall result. So that should not be an issue anymore in branch 5.2 starting with 5.2.5.

Now back to the log messages, they didn't suggest that Kamailio is frozen, but that Kamailio didn't accept the tls connections because of mismatching the method or no common ciphers.

Did kamailio route the usual SIP traffic when this check was done by AWS R53?

What is the TLS method you set in tls.cfg?

Cheers,
Daniel

Btw..I saw the git repo on the bug.  I also experienced libcrypto coring and was told 5.2.5 would fix it.  However, in my case libcrypto didn't core.  Kamailio basically just stopped sending any responses back to tcp ping requests from R53 (or even telnet 5060 didn't respond).

Hi Karsten,

These are our current settings:

root@sjoprodkama51:/var/log # grep max_connections /etc/kamailio/kamailio.cfg
tcp_max_connections=32768
tls_max_connections=32768
root@sjoprodkama51:/var/log #

which seems more than enough I would think.

Thanks Jurijs.

We just upgraded to 5.2.5 to support openssl 1.1.1 which is required for ubuntu 18.04.  Is it possible to have back port this fix to 5.2.x release since we just released 5.2.5 through our battery of QA testing?

Hi Andrew,

I'm pretty sure this is bug what you are talking about:


It should be fixed in 5.3.0 I believe, or you can always downgrade openssl to 1.0 as described here:

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:

tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

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:
