A significant part of sql server process memory has been paged out.
This may result in a performance degradation. Duration: 0 seconds.
Working set (KB): 349620, committed (KB): 686376, memory utilization:
50%.
Has anyone been able to solve this problem on SQL Server Std Edition ?
I know the OS is trimming the Memory but apparently I have been
unable to find a way for this to stop.
"lock pages in memory" is disregarded in Std Edition.
Any thoughts ?
Add RAM to the box (or if there is more than 686 MB, increasing the amount
of money allocated to SQL Server)?
Lighten the workload?

If it is the OS that really needs the memory then you probably want to
place a limit on SQL Server so that the max memory it uses leaves
enough for the OS. Starving the OS for memory guarantees poor
performance.
If there is some other application causing the memory shortage you
probably want to see if that application can be controlled.

Make sure your drivers and OS and sql server are fully patched. There are

The Box has 12GB of RAM.
SQL Server max memory is set to 8GB.
Windows is patched to SP2.
I am copying though "very large" backup files (around 70~100GB ) from
and to the box.
Is there *anything* I can do?

I have to correct the data:

SQL Server max memory is 10GB
The rest is the same.

1) there are other scripts copying *very large* backup files around.
2) this is x64 SQL Server 2005 Standard Edition built 3161
3) It *does* happens when copying those large files
Now, is there a way to prevent this Huge Memory Flush ?

1) there are other scripts copying *very large* backup files around.
2) this is x64 SQL Server 2005 Standard Edition built 3161
3) It *does* happens when copying those large files
Now, is there a way to prevent this Huge Memory Flush ?
-Noel
A significant part of sql server process memory has been paged out.
A significant part of sql server process memory has been paged out.
This may result in a performance degradation. Duration: 0 seconds.
Working set (KB): 349620, committed (KB): 686376, memory utilization:
50%.
Has anyone been able to solve this problem on SQL Server Std Edition ?
I know the OS is trimming the Memory but apparently I have been
unable to find a way for this to stop.
"lock pages in memory" is disregarded in Std Edition.
Any thoughts ?Add RAM to the box (or if there is more than 686 MB, increasing the amount
of money allocated to SQL Server)?
Lighten the workload?

If it is the OS that really needs the memory then you probably want to
place a limit on SQL Server so that the max memory it uses leaves
enough for the OS. Starving the OS for memory guarantees poor
performance.
If there is some other application causing the memory shortage you
probably want to see if that application can be controlled.

I have to correct the data:
The Box has 16GB of RAM.
SQL Server max memory is 10GB
The rest is the same.|||1) You did not answer my question about other services/apps running on this
box.
2) What version and is it 32/64 bit of sql server are you running?
3) Consider setting minimum sql server memor to see if this prevents the
paging. Also, have you been able to tie the paging to a specific event on
the server?

A significant part of sql server process memory has been paged out
On a SQL Server 2005 x64 Standard Edition cluster I get the error listed below and then the SQL server service restarts. The SQL server is unavailable for 5-10 minutes during that time. Any ideas?
Error:
A significant part of sql server process memory has been paged out. This may result in a performance degradation. Duration: 647 seconds. Working set (KB): 11907776, committed (KB): 28731732, memory utilization: 41%%.
This means that Windows has decided to move SQL Server memory out of RAM and stored it in disk until it's needed again. This article has some more information on how to avoid this:
http://support.microsoft.com/kb/918483/en-us
You also mentioned that SQL Server has restarted after this. Could you please post the last 10 lines or so of errorlog when this occurred?
Thanks,
Fabricio.
|||I did look at that article but I don't think that will work for SQL Standard Edition.
Note SQL Server 2005 Enterprise Edition is the only edition that is designed to use lock pages in memory.
|||In that case, try to identify what's causing Windows to page SQL Server out to disk. SQL Server tries to fill up the available memory on the machine. When you have other apps running on the same machine, they may use a lot of memory and push SQL Server out to the swap file. SQL Server will detect this and trim its memory, but in some rare cases it can't release enough memory or can't release fast enough and may end up being swapped out. This message is to notify you that such event happened and that SQL Server's memory is being fetched from disk, causing some temporary slowness.
Please, let me know if you need help figuring out what app is using memory on the machine.
Thanks,
Fabricio.
|||I believe the KB article is incorrect stating it’s only valid for x64 Enterprise Edition. I encountered the same problem you reported and the Lock Pages In Memory policy work just fine with x64 standard edition.
|||This article explains the problem I was having:
http://blogs.technet.com/askperf/archive/2007/05/18/sql-and-the-working-set.aspx
The system was running Windows 2003 SP1. Have upgraded to Windows 2003 SP2 and have not had the problem since.
|||Kmoskal,
The KB article is correct. Only SQL Server Enterprise will lock pages in memory. You may set the priviledge with any other edition, but it will have no effect in SQL Server. I guess you just have been lucky (and SQL Server has been doing a great job keeping itself in RAM) :-)
Thanks,
Fabricio.
