I am running into a situation where the nathelper module is causing openser/kamailio to
crash. The crash occurs when opensbc sends and invite to openser with an extra CR in the
message body. I already contacted the opensbc folks about this. I just wanted you all to
be aware that this could cause serious service interruptions.
Error log:
kernel: [599650.771067] kamailio[25461]: segfault at 18 ip b7a0a6c7 sp bfbaaa70 error 4 in
nathelper.so[b79f7000+18000]
Sample invite sent to kamailio.. Please look at the extra CR/LF after Supported. The
nathelper module crashes after this.

i think daniel fixed this a few days ago. try with kamailio 1.5.
perhaps the fix is also in 1.4, but i'm not sure.

Thanks for your reply,
I am using v 1.5, perhaps downloading the latest from CVS?

Juha,
I tried the latest from svn and I still have the same problem. Any other ideas?

get core dump and check with gdb 'where' command where the crash takes
place.

I'm sorry the server is not crashing, it's the kamailio application that is
crashing. You see a segfault in the log that I sent.

Hi Carlos,
yes, i was refering to the kamailio server, sorry if i was a bit unclear. :-)
It would be really helpful if you could try to generate a core file and then
print a backtrace as described in the wiki article given previously.
Cheers,
Henning
