Re: [SR-Users] kamailio coring ver 5.1.2

Hello, first it is really recommended you run at least latest 5.1.x version, the 5.1.2 is old in 5.1.x release series and many bugs may have been fixed. Even more, 5.1.x is no longer maintained, so I would strongly recommend to upgrade to latest in series 5.3.x or 5.4.x. Then, searching on google on Bad RIP value returns mainly discussions about Kernel panic. According to this article: * https://www.opensourceforu.com/2011/01/understanding-a-kernel-oops/ RIP is the CPU register containing the address of the instruction that is getting executed. Without a clear corefile with backtrace pointing to kamailio, it is not easy to say if Kamailio has anything to do with or there is some linux kernel issue on your system. Try searching on google, there should be some hints to try to troubleshoot by ip and sp values, maybe you can get further details.
