Thanks Daniel for pointing out, so if I upgrade my Kamailio it should all go away , right. Will do a version upgrade and check similar calls.

I've seen very similar crashes EOF on 11, EOF of 16 etc etc in few other situations as well, while at once such occasion it was an invalid kamctl command and it crashed kamailio(Another thread maybe)

If Kamailio crashing before it can even get some route started then we can't perform sanity checks and hence even if I've DNS SRV, LinuxHA, or anything the caller might keep trying call over and again and keep crashing the whole layer :)

Hello,

looks like there were updates to dialog modules in 4.1 after 4.1.4. The code lines do not match the back trace.

You should upgrade to latest version in 4.1 branch -- there is no change that you have to do in kamailio.cfg or database.

Meanwhile, we can see the relevant pieces of code from your specific version with following commands in gdb:

frame 0
list

frame 4
list

Cheers,
Daniel

Hello,

can you give the output of 'bt full' in gdb to see where it actually crashed?

Cheers,

Hi,

I'm randomly getting crash in my Kamailio with an error in log files like this:

<core> [pass_fd.c:293]: receive_fd(): ERROR: receive_fd: EOF on 19

ALERT: <core> [main.c:775]: handle_sigs(): child process 6853 exited by a signal 11

Version of Kamailio is:

compiled on 03:48:50 Aug 1 2014 with gcc 4.4.7

And gdb bt output is attached in text file.

One thing out that is common in all the previous core files is this:

#12 0x00000000004a54ab in receive_msg (

buf=0x924600 "INVITE sip:+17036833500@14.131.165.9:5073 SIP/2.0\r\nVia: SIP/2.0/UDP 14.55.2.43:5060;branch=z9hG4bK0eB8f68591a19b9b8f0\r\nFrom: \"Anonymous\" <sip:Anonymous@Anonymous.invalid>;tag=gK0e13e132\r\nTo: <sip:+170"..., len=1018, rcv_info=0x7fff3dbee970) at receive.c:212

#13 0x000000000053c9a8 in udp_rcv_loop () at udp_server.c:536

Does this mean that Kamailio can't understand the From Domain: Anonymous.invalid and hence crashes ?

Thanks,

Sammy
