Sorry...

Try with some tool to see what type of traffic. 
(Munin,cacti,ganglia, etc)

Is in your lan?

Asunto:  Outbound traffic spike every 30 minutes
Enviado: 3 de dic de 2013 19:36

Since Sunday morning, one of my CentOS servers has been generating a 
small spike of outbound traffic every 30 minutes (X:00 and X:30). It's 
not enough traffic to really cause any notice except for the fact that 
it is a very regular pattern and it started abruptly at midnight Sunday.

This server is used for mail (Courier-MTA), and DNS (Bind).  I cannot 
find anything unusual in either of those logs.  I tried grepping through 
my firewall logs, but have been unable to find anything useful there 
either.  I don't see any cron jobs that would generate network traffic.

Any suggestions how I can go about tracking this down?
