[SR-Users] Kamailio 4.2.4 segfault and crash

[Daniel-Constantin Mierla]

Hello,

you can place any new modules in old version of kamailio, but they were
not tested and not supported officially by the project. Anyhow, if you
get an issue with a new public module, likely it is in the master branch
as well and we will fix it if you provide the backtrace when it happens
again.

The statsd module is now in master branch of Kamailio repository, you
don't need to take it from eloycoto repository. Eloy is maintaining it
in Kamailio project as well.

Cheers,
Daniel
