Thanks Daniel for pointing out, so if I upgrade my Kamailio it should all
go away , right. Will do a version upgrade and check similar calls.

I've seen very similar crashes EOF on 11, EOF of 16 etc etc in few other
situations as well, while at once such occasion it was an invalid kamctl
command and it crashed kamailio(Another thread maybe)

If Kamailio crashing before it can even get some route started then we
can't perform sanity checks and hence even if I've DNS SRV, LinuxHA, or
anything the caller might keep trying call over and again and keep crashing
the whole layer :)
