    The tmp variable is not intialized by default, so it can be anything
    therefore the out of bounds value. It used only when printing some
    errors, so it didn't get a proper value as no such error was printed
    for you case.<br>
    <br>
    The backtrace shows the process in in recvfrom(), so it waits for
    traffic from network. That is the case when the processing of former
    sip message was finished and now Kamailio waits to receive another
    one.<br>
    <br>
    If you run centos, be sure you don't have limits in selinux rules -
    better disable it completely and test again. Also, be sure you don't
    have limits in the firewall, especially contrack module and sip
    firewall modules in the kernel.<br>
    <br>
    In kamailio.cfg, if you have pike module, be sure you don't drop
    good packet with this module.<br>
