This 'udp();' is probably your culprit.  Most likely, the machine called
'inoc-cabin3-17' is chugging off a 'MARK' every 20 minutes because it hasn't
logged any *other* syslog traffic in the interim (very handy so you can tell
the difference between "machine crashed sometime between 11:34PM (last msg)
and 8AM when we found it dead" and "machine was alive at 3:45 because it
MARK'ed, and dead at 4AM because it didn't"...)

Now, if you don't know who 'inoc-cabin3-17' is, that's a *different* problem ;)
