This sounds like a common problem that certain data center environments
run into with 10 Gb/s and higher loads.  In a nutshell, a simple
throw money at it solution to the problem is to use a switch with larger
buffers.

Nonetheless, there are plenty of good sources of material about the
phenomenon, such as:
