Our Exchange server (W2K, Exchange 2K) is behaving very nicely, no complaints. However, while checking the event log recently, I came across this:
Category: Database Page Cache
Event ID: 474
Information Store (3184) The database page read from the file "C:\Program Files\Exchsrvr\mdbdata\priv1.edb" at offset 43167592448 (0x0000000a0cfd3000) for 4096 (0x00001000) bytes failed verification due to a page checksum mismatch. The expected checksum was 2334747747 (0x8b296c63) and the actual checksum was 1972333934 (0x758f6d6e). The read operation will fail with error -1018 (0xfffffc06). If this condition persists then please restore the database from a previous backup.
I've done some preliminary research which suggests some imminent failure of my storage subsystem. Is this necessarily the case? As I said, it's working fine! Do I need to panic?
