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
