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.
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. 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. In kamailio.cfg, if you have pike module, be sure you don't drop good packet with this module.
