Re: [SR-Users] kamailio-5.2.0 Crash - udp_send failed

Hello, you are using a old and non released dev version of kamailio. These are meant only for development purposes. Please update to a proper version (like the latest one based on 5.3 or 5.4 branch. Then try to reproduce the bug again and report on the list or by creating an issue.
