Problems with cfengine

[Anton Krall]

Guys...  I run cfengine on my wkrstations like this
/var/cfengine/bin/cfagent -I and it runs every hours... Every so hours I get
emails like this:
 
%Subject: Cron <root@tvoxvideo2> /var/cfengine/bin/cfagent -I
%
%!: Protocol transaction broken off
%!: Authentication dialogue with intruder.com.mx failed
%!: Unable to establish connection with intruder.com.mx (failover)
%

Whats wrong? Why is this been sent every so often?

Thx!
