SBS 2011 - Exchange event 474


We may have sustained an unexpected shut down on our SBS 2011 server.

We have received a single event log indicated below.  However, mail flow is normal and the Information Store is mounted.  All services are started normally.  There do not appear to be any issues.  

•Should I just monitor the server and see if the event returns?
•Alternately, should I plan on taking pro-active measures?  If so, what action should be taken?

Log Name:      Application
 Source:        ESE
 Date:          3/14/2016 10:53:46 AM
 Event ID:      474
 Task Category: Database Page Cache
 Level:         Error
 Keywords:      Classic
 User:          N/A
 Computer:      RGS-MAIN.rgs.local
 Information Store (4964) Mailbox Database: The database page read from the file "D:\Program Files\Microsoft\Exchange Server\V14\Mailbox\Mailbox Database\Mailbox Database.edb" at offset 120023515136 (0x0000001bf1f58000) (database page 3662826 (0x37E3EA)) for 32768 (0x00008000) bytes failed verification due to a page checksum mismatch.  The expected checksum was [6db46db4e73f7f2d:3987c6783921931e:3e2ac1d5ba1a0587:15cbea3453ca9ebf] and the actual checksum was [93d96c26050262eb:3987c6783921931e:a017a017ba1a0583:69cb963453ca9ebf].  The read operation will fail with error -1018 (0xfffffc06).  If this condition persists then please restore the database from a previous backup.  This problem is likely due to faulty hardware. Please contact your hardware vendor for further assistance diagnosing the problem.
