Hardware error: machine check events? Process 2 below temp

New install Dell Poweredge 620 server.

Install OES11 with SLES SP2 combo dvd.

Anything below a concern that I have a hardware issue?

Install seems fine, but when I look in messages and warn the following messages appears:

Any concern here? The NOS installation is SLES11 SP2 with OES11 SP1 Added on.
