You know how we set all the ports on the switch to 100 full duplex? Yeah, well... we never set the machines themselves to be full duplex. The linux drivers (on all the database servers) detected it fine, but the freebsd drivers (for the same NIC) didn't, so we had to go and explicitly turn it on.
All seems to be working now? (that was to myself.... no need to reply)
Wish Dormando was around. I hate working on servers. Mad props to evan and raja for helpin' a brotha' out, though. *pour* *pour* Now to go drink the other 38 oz.
