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
