Hello,

you should upgrade at least to the latest version in branch 3.1 to be sure it is not related to a fixed issue. From 3.1.2 till 3.1.6 were many issues fixed in that release series. It does not require any change to database or config file. If still happens, then send again the back trace, it will have the right pointers in the source code for the branch 3.1.

Overall, you should consider upgrading to one of the latest two stable releases, because they are maintained by the development team. For older releases you are more on your own.

Cheers,
Daniel

Kamailio is generating a abort at qm_debug_frag function (BUG: qm_*: prev. fragm. tail overwritten) but I can't understanding the meaning this abort...  Someone can tell me the purpose of qm_debug_frag function, it checks if some improper memory handling happened and abort the program?

Below is backtrace of abort:
