Racluster packet/byte counts off

Hey Nick,
You may be truncating your pkts count because of a small field width.
Try "pkts:12" to see if your digits comes back.
The tools are suppose to put a '*' at the end of fields that have been 
truncated
due to the width field being too small.  I may need to fix that if this 
is all there
is.
