Night before last I started getting the following message in /var/log/messages about every hour or so. Nov 23 11:39:50 <machine name> kernel: [54140.456113] EDAC MC0: CE row 1, channel 1, label "": (Branch=0 DRAM-Bank=2 RDWR=Read RAS=15602 CAS=460, CE Err=0x10000 (Correctable Patrol Data ECC)) Does this mean I have a memory module about to go out?
