Having installed 2GB more memory, the interfaces on the quad nic now seem to be experiencing corrupt packets. Also put the nic into a different machine with 4GB ram and tested there, with the same results (to rule out faulty memory). Nothing else in the environment has changed. Removing the additional 2GB of memory restores functionality.
