Hi Daniel,
We were running the kamailio without any issue after changing the shared
memory to 1024. We dont have any issue on last two months.
But today we got the issue and we are not able to connect new tls
connections.
Dec 15 08:13:56 webrtc /usr/sbin/kamailio[19550]: ERROR: tls
[tls_server.c:190]: tls_complete_init(): tls: ssl bug #1491 workaround: not

There is no crash, it is only low memory and new connections not occuring.
Can you suggest what can be the resolution here ?. Do we need a process
restart to free up the memory resource ?.
Regards

Hello Daniel
Could you look this ticket with attached backtrace
https://2600hz.atlassian.net/browse/KAZOO-5699
I not sure where is root of issue. May be your comment clean this.

Still curious if you got a core file so far (or
it was just those error
messages) and if yes, it would be good to get the backtrace.
Cheers,
Daniel

Thanks Daniel. We have increase shm memory to 1024 from 64 and private
memory to 64 from 8MB.
We will closely monitor and will update the thread if encounter any issue.

Hello,
these errors do not indicate a crash, but unability to read due to low
available memory. Did you get a crash (kamailio stopped)? If yes, any core
file from where you can extract the backtrace?
Anyhow, as hint, if you use a lot of tls, increase the size for shared
memory, it is needed a lot there.
Cheers,
Daniel

Hi all,
We were using kamailio 4.4.5 and we enabled only for webrtc.
We were observing two memory crashed in last two weeks.

Is there any known issue for tls module in kamailio_4.4.5 ?. We are
using default 64MB for shared memory and 8MB for private memory. Do we need
to increase this ?.
Regards
Andrew
