In case it helps anyone using Dell R410 / 610 / 710 etc. servers: I have had machines lose their eth connections periodically (CentOS 5.4 bnx2 driver). Seems like a bug with the Broadcom NIC drivers. [luckily read of it on a Dell mailing list]
Bug Reports: http://kbase.redhat.com/faq/docs/DOC-26837 http://patchwork.ozlabs.org/patch/51106 Not sure yet if this is exactly my issue but I'm giving it a shot now. Thought I'd post since, anecdotally I've seen many people use these servers on the list. -- Rahul
