Thanks, it's a bit hard to try and translate this into some we can understand.  
:-(

Thanks not good.  This means that the interrupts are not being serviced fast 
enough to keep up with the traffic.  With 5 networking ports it doesn't 
surprise me.  What kind of tests are you running to cause this?  It's unclear 
if this system can withstand the traffic from these ports.  Have you tried to 
run the test on a single port to see if the drops happen then as well?  Try to 
see where the problem starts to happen.  Are interrupts being shared between 
the devices?  What OS are you running?

Cheers,
John
