Re: [SR-Users] Kamailio crash [receive_fd: EOF on 19]

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,
Daniel

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

_Version of Kamailio is:

And gdb bt output is attached in text file.

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

#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
