Hello. I Installed kamailio on ubuntu 14.04 that runs as virtual systemOpenVZ. after starting kamailio I see that it runs ok with kamailio start or kamctl start at ps -ax I see working processes. But after one minute of working kamailio fails with kamailio: ERROR: <core> [daemonize.c:315]: daemonize(): Main process exited before writing to pipe I see nothing more at debug file. No errors.
