Hi Daniel,
Unfortunately I cannot reproduce the issue any more as one of the servers involved is no longer available (the one returning the 404 after the redirect).
Luckily I have another core generated back then which happens to be 10x bigger in size:
-rw------- 1 root kamailio 88371200 Dec 1 07:32 core.kamailio.5062.14cn5.lax1.gogii.net.1480606368 -rw------- 1 root kamailio 8611196928 Dec 1 19:35 **core.kamailio.14300.14cn5.lax1.gogii.net.1480649729**
I'm attaching both "bt full" and "info locals".
Let me know if these are OK or if they are bad too.
[backtrace-bt_full.txt](https://github.com/kamailio/kamailio/files/685940/backtrace-bt_full.txt) [backtrace-info_locals.txt](https://github.com/kamailio/kamailio/files/685941/backtrace-info_locals.txt)
If we can't get anything useful from this core than I think we cannot move forward.
Thanks, Joel.
