Message

Hi All,
Our SQL server is logging following message. Most of these message are
logged by spid 2: (lazyWriter)
SQL Server has encountered 1 occurrence(s) of IO requests taking longer than
15 seconds to complete on file [I:\XXX_Data.MDF] in database [XXX] (17).
The OS file handle is 0x00000554. The offset of the latest long IO is:
0x000000175b8000
Any idea how can i get to the bottom of it.
Thanks

vt
run DBCC CHECKDB command to see what is going on.

|||Hi,
This message was introduced from SQL 2000 SP4. This denotes that I/O
processing of SQL Sever is slowed down. This normally comes if the disk
write speed is slow down.
Take a look into the below URL:-

|||Hi hari,
I know that its a disk performance problem.. Ours is a RAID5 setup.
We have done the disk diagnostic, but it came up with no errors...
Another question is why LazyWriter process is logging it..

|||Take a look at Performance Monitor disk counters, particularly disk queue
length. A value that averages more than 2 * the number of physical disks in
the logical drive indicates a bottleneck. Distributing the workload over
more disks can help, either by adding more drives to the array or placing
database files on other drives/arrays. If you do a lot of writes, use RAID
10 instead of RAID 5.
Hope this helps.
