Hello,

might not be the same, but I just pushed to branch 4.0 a fix for the case when a request has both Proxy-Authorization and Authorization headers that led to a wrong selection of the credentials, ending up in a crash. Pull the latest branch 4.0 and try to see if goes fine this time.

Before starting kamailio, enable core dumping via:

ulimit -c unlimited

in the terminal. Also, if you have /etc/default/kamailio, edit to enable the core there. On some systems, you need to run kamailio as root, because the kernel forbids dumping core files for unprivileged users. The coredump file allows to get the backtrace and identify what was the line of code causing the issue.

Cheers,
Daniel

Hi Guys,

We had our kamailio instance crash today, it appeared to be after multiple registration failures, the resulting logs showing;

Any comments welcome.
