Hi Daniel, Ok great will try that. Ive just had another crash today on same release, this time affecting the child processes, please see below. I presume again I would need to capture debug/traces at the time of failure to see possible cause?

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.
