Hello,
I tried to reproduce with a very simple config to handle register
requests. So I sent a REGISTER with expires 60 (very much the same as
the one in the trace you sent), waited a while, then sent two REGISTERs
having the CSeq incremented. All went fine.
I tested with master and 3.1 branches (so the last is actually 3.1.5).
Can you upgrade to 3.1.5 first and try again? If still fails, then
update config to print the return code for save() function, something like:
$var(r) = save("location");
xlog("code returned by save is $var(r)\n");
if($var(r) < 0)
send_reply("500", "Failure");
Let me know the value of the returned code for the register that does
not have a contact in reply.
Cheers,
Daniel

Hi Daniel-Constantin,
I send you the PCAP and LOG files corresponding to one of these
situations. As you can see in the LOG file, one thread (5444) handles
the first REGISTER, other thread (5447) handles the second REGISTER
(retransmission) and a third thread (5451) indicates that the binding
has expired, six seconds after the arrival of both REGISTERs.
Thanks again.
Alejandro.

Hi,
Since we installed last version of Kamailio (3.1.4)
the last version is now 3.1.5, but this is not really the most
important aspect. However, it is recommended to upgrade, there were
some fixed to registration handling when register requests have
multiple contacts.
we have been experiencing a big problem with REGISTER
retransmissions. When the server receives a retransmitted REGISTER
it removes the binding and the UAC remains unregistered until next
refreshing period. I include a PCAP capture that shows this behaviour.
I am not 100% sure that this problem never happened with older
versions.
Has anybody experienced the same problem?
I will try to reproduce and investigate myself. Anyhow, meanwhile
maybe you can provide more hints faster. Do you have error messages
in the syslog? Can you run with debug=4 in config file and send the
output in syslog for such a case?
