[SR-Users] segfault at 18 error 4 in auth_db.so on Version 4.0.6-1 Release

Thu Jun 26 11:07:50 CEST 2014

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?
Thanks
Jon

    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
