Dear David-

We had a similar problem with a cluster of R610's.  That cluster is  
running RHEL 5.3 and has broadcom 5709 NICs.  It turned out to be a  
redhat issue specific to the broadcom 5709.  Your problem sounds  
similar enough that you might want to check the bug list for centos.   
Here is the link to the redhat knowledge base article:  http://kbase.redhat.com/faq/docs/DOC-26837
