Sounds a lot like permission problems.
First, which distro are you using? I will assume you are on raspbian/jessie,
but let us know if this is not true.
Debian/jessie is systemd based, so please forget about “service XXX
start|stop|restart” and use “systemctl start|stop|restart XXX.service”
Check permissions of /dev/i2c-1:
$ ls -l /dev/i2c-1
crw------- 1 root root 89, 1 Sep 1 09:16 /dev/i2c-1
enable owserver at boot
$ sudo systemctl enable owserver.service

Try these commands (as root or with sudo) and see if systemctl records some
useful info with
$ sudo journalctl -u owserver.service
Hope this helps
S.
PS:
I just noticed that the LSB scripts in raspbian/jessie are bugged: they return
with a success status even if owserver failed to start… So do not trust to much
systemctl status, but always check if the owserver process is really running.------------------------------------------------------------------------------
