Something wrong with hardware? This is an ECC memory correction. It is OK to see it once in a while, since even 100% working DRAM has failures from time to time (called softerror rate) - therefor the need to have ECC in important systems If however you see a lot of them it is time to replace the faulty memory. -- B.Walter http://www.bwct.de http://www.fizon.de bernd@bwct.de info@bwct.de support@fizon.de
