Subject: NIU - Sun Neptune 10g - Transmit timed out reset (2.6.24)

Hi.

I get errors like this after a few minutes of traffic on a Sun Neptune 
10g ethernet card. (with nice 500MB/s throughput).

Then the server seems too busy with something, so it doesn't even 
respont to a serial terminal login.
