Intel EtherExpress 16 TX issue

I've ran into an issue with an Intel EtherExpress 16 card. When running
Webstone on an Apache server (Intel Deskside Xpress SMP, using 2.0.33
with aic7xxx patch), the system locks up tight - no keyboard response,
non-ping'able, etc. I've noticed that the TX-DRP rate increments with
time, then finally locks up after about 1800 dropped transmit packets.
I've set the window size to 4096 (with 'route'), and gives about 7100
dropped transmit packets. I've only seen this when using Webstone, and
happens for both cards. Any suggestions and/or work arounds.

Here is the output of the last 'netstat -ainc':
