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.

Cheers,

Henning
