eth0: can't fill rx buffer (force 1)!

Hi,

I have posted on this issue back in April. As recommended, we had made
changes to /proc/sys/vm/bdflush:

40      0       0       0       100     500     200     0       0


However, the problem resurface lately. The default route of the server
would 'disappear', halting all services.

Here's the server info:
Linux version 2.4.18 () (gcc version 2.96 20000731 (Red Hat Linux 7.1 2.96-81))

Is the bdflush setting alright? What else can we finetune?


Thanks,
