I have been getting this error message sometime. Server is running Exchange 2007 on Windows Server 2008 R2
ID= 508; Src= ESE; User= ; Catg= Performance ; D/T= 09/16/2014 19:07:08; EventDesc= MSExchangeIS (6384) First Storage Group: A request to write to the file "E:\ExchangeSvr\Mailbox Database.edb" at offset 122073874432 (0x0000001c6c2b8000) for 8192 (0x00002000) bytes succeeded, but took an abnormally long time (62 seconds) to be serviced by the OS. This problem is likely due to faulty hardware. Please contact your hardware vendor for further assistance diagnosing the problem.
What has caused this error?
