strange records

David,

I don't know if this will help but it may be two things.  I was pushing
about 30-40 Mb/sec
on Solarus full-dup 100base-T and had to do a few things to make it sing.

	- Installed a new version of libpcap, 0.4
	- changed all varables in my clients to accomidate 64 bit length (long
long).
        This was needed when I crossed over the 20 Mb/sec mark.  I.e.
pumping
	  lots of data for hours on end.

Sometimes when I had different versions of the argus server and it's clients
compiled
with different versions of libpcap the clock would get far off and
occasionaly the
data would get wacky.  I just made sure that all code was compiled from the
same
base libs.

I hope this helps.

	...Chas
