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. 

Oct 10 01:03:03 webrtc /usr/sbin/kamailio[18002]: ERROR: <core> [tcp_read.c:1321]: tcp_read_req(): ERROR: tcp_read_req: error reading - c: 0x7f21ea8f6198 r: 0x7f21ea8f6218

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
