[Service]

Hello,
I believe this issue is related -
https://github.com/kamailio/kamailio/issues/1172. We encountered the
problem before and the solution is to link kamailio-tls-modules with
libssl1.0.X instead of libssl1.1.

Hi,
Just to add that in my case I had a problem when after some period of time
with a lot of TLS clients(100k+) I got a lot of TCP connections in
CLOSE_WAIT state. When connections in CLOSE_WAIT state hit more then 1k,
then kamailio stopped to receive traffic via TLS, nevertheless UDP at same
time worked fine. From my point of view it looked like there was issue
somewhere on Linux side, cause Kamailio never got anything... At least this
is what I remember... I still plan to work on it someday. :) And if I will
find out, I'll let you know.

But that's all, no further processing by kamailio.

Hi kamailios,
i have a creepy situation with v5.2.1 stable Kamilio. After a day or
so, Kamailio stop to process incoming SIP traffic via TCP. The
incoming TCP network packages get TCP-ACK from the OS (Debian 9,
4.18.0-15-generic-Linux) but Kamailio does not show any processing for
the SIP-Traffic incoming via TCP. No logs, nothing. While traffic via
UDP is working just totally fine.
When i look via command "netstat -ntp" is see, that the Recv-Q get
bigger and bigger. e.g.:
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program
name tcp 4566 0 172.17.217.12:5060 xxx.xxx.xxx.xxx:57252 ESTABLISHED
31347/kamailio
After Kamailio restart, all is working fine again for a day. We have
maybe 10-20 devices online via TCP and low call volume (1-2 call per
minute). The only settings for tcp we have is "tcp_delayed_ack=no"
How to could we debug this situation? Again, no error, no warings in
the log. Just nothing.
Kristijan
