2.1.124 Sockets sticking under load

Hi,

I checked the kernel list and didn't see anything like this, so here goes.
2.1.124, SMP enabled, Dual P90 with 256(central,www) and 128(storage,ftp).
Running MySQL between the two machines. Loads get heavy, 3-5 range. Storage
usually does better in the 1-2 range. Net goes unresponsive, new attempts
from central to storage for MySQL time out even when MySQL is restarted.

central: up 10:50
storage: 2 2:07

Both machines have hung their network interfaces for 2-3 minutes at a time,
to the point that I have a script that runs and downs then re-ups them if a
ping to the router fails.

Any thoughts?
