[realtek-bug] Realtek 8139C problems, linux 2.2.19

[Dan Miller]

We've been having a variety of sporadic problems with the Realtek driver, V1.17, under linux 2.2.19.  Most recently, we left a system running over the weekend with the WebStone test (500 connections) running through our machine.  After running for a few hours, it displayed the following series of messages, and the ethernet interface quit functioning.  

We could restore system functionality by downing and uping the interface, but the system is VERY low on memory; I'm enclosing the meminfo output after the crash.

Do you have any insights into what's going on here??
