Hyperactive cron vpn task?

[SnakeByte]

my /tmp/syslog.log is filled with this:
Jan 29 20:00:01 crond[465]: crond: USER administrator pid 2069 cmd service start_vpnclient1
Jan 29 20:00:01 rc_service: service 2070:notify_rc start_vpnclient1
Jan 29 20:00:01 syslog: VPN_LOG_NOTE: 84: VPN Client 1 already running...
Jan 29 20:01:01 crond[465]: crond: USER administrator pid 2147 cmd service start_vpnclient1
Jan 29 20:01:01 rc_service: service 2148:notify_rc start_vpnclient1
Jan 29 20:01:01 syslog: VPN_LOG_NOTE: 84: VPN Client 1 already running...
Jan 29 20:02:01 crond[465]: crond: USER administrator pid 2186 cmd service start_vpnclient1
Jan 29 20:02:02 rc_service: service 2187:notify_rc start_vpnclient1
Jan 29 20:02:02 syslog: VPN_LOG_NOTE: 84: VPN Client 1 already running...

Something is running every minute that has to do with VPN. The VPN client seems to be working fine. (I can pass traffic through it just fine).

Is this cron job necessary? What's it doing and why do often?
