Do you have those defined in /etc/group and /etc/password /etc/shadow?  If
so, change them to

        config set_gid: snort
        config set_uid: snort

See if that makes a difference.

There's no port on the first half of the rule.

        log udp 192.168.0.12/32 any -> 192.168.0.111/32 514 (logto: \
        "ws1.log" ;)

All rules must have the following form:

        <action> <type> <IP> <port> <direction> <IP> <port>

More is fine:

        <action> <type> <IP> <port> <direction> <IP> <port> (<whatever>;)

Or not....  :)
