Poweredge 2850 Error EB107 PROC INIT ERROR

Greetings All,

Have a 2850 that's been restarting on its own the past 3 days, nothing in the dump files.  Today the machine pops an error on the amber LCD screen  - EB107 PROC INIT ERROR.  It's a dual CPU unit with twin Xeon 3.0GHz procs  and boots up, but I can't find anything on this error.  Is it the proc or the MB?  Or could it be something else?

Thanks in advance

Pyke
