git
OpenVZ have an issue with linux headers. When I run uname -r it give me heades 2.6 that works at the host server. Ubuntu have 3.13. 
I think it may be main reason of this issue or simphtom af another issue at OpenVZ systems...

If deb:
  I would say that you should use /etc/init.d/kamailio start
  check /etc/defaults/kamailio too
