While I won't rule this out, my local hardware vendor does a 48 hour 
burn-in including a full gamut of tests (including memory) before 
handing over the servers. These servers are less than two weeks old...

Seems like this is a common type of error in some situations. I 
tried to boot in kexec/kdump mode (CentOS 5 replacement for 
diskdumputils), but the e1000 driver isn't seeing the NICs after a 
reboot via the "capture kernel", so I can't replicate the (rsync 
induced) problem and perform kernel debugging. I'll explore this 
more tomorrow.
