Out of Memory Error (Win7 x64 8GB Ram)

Strange thing just happened. I got an out of memory error from Windows 7 x64 telling me to shutdown programs. I am running Windows 7 x64 and 8GB of ram leaving system on 24/7. I checked the task manager and 7.96GB were being utilized. I have been running the same setup for over a year and this is the first time I have recieved this message. Makes me wonder if it was a Windows auto update. I had left AutoCAD 2009 and Internet Explorer up and running for several days, but I have done this before without issue. I also had some open Excel spreadsheets open over VPN from main office. I looked at the task manager but the programs memory usage did not add up to 7.96GB. I just restarted. Lets see if it happens again.

Have you turned your pagefile off? If so, turn it back on.

My page file has always been on. It is set to default (let Windows manage). Page file size is defaulting to 8191MB under Windows management. However, down below it recommends 12,286MB. It is strange that Windows is not defaulting to the recommended value.

Could be an application has a memory leak.

Ok, I changed the page file to custom and set Initial size to 12,286MB x1.5 and Max size to 24,573MB x3.0 (Physical 8191MB). Lets see if I still get the error. If it was a memory leak is there a utility or tool I could use to track down the culprit.

Ok, I did not realize at first but under windows page file management I had a Commit charge of 34GB and a page file of 28GB. I guess there has to be a major memory leak somewhere. Those are huge numbers.

I have been having issues with my setup as well.
I run 24/7 and after 8-9 days all of the memory is allocated to something, memory usage doesn't add up to 8GB, and my hard drive pages like crazy just doing little things like opening up a browser.
I reboot and all is fine for 8 or 9 days and then it repeats.
this started maybe 2 months ago at the most.

About 2 months seems to be the same for me as well. Looking at my event viewer logs the first memory error was on 1/28, which is about 10 days after I got back from vacatiion and powered up my computer again. It seems everthing is fine for 8-10 days. Maybe this was caused by a x64 update issued by Microsoft. I have auto-update turned on and I am using Microsoft security essentials. The programs I primarily have running all the time are Photoshop CS4, AutoCAD 2009, Outlook, Internet Explorer, & Adobe Acrobat 9 Pro.

Dear OP,

please check the following URL from Microsoft. I am only normal Windows user so cannot provide further detail how to do diagnostic. The pros in the forum maybe able to help further.

The only apps I have running all the time are Steam, Outlook 2010, Firefox with 10 tabs, and Nod32.
Apps I run occasionally are Photoshop CS5 and Acrobat 9 Pro but I close them when I am done with them.

Windows 7 recommended page file size is min and max equal to the size of your memory. Windows Vista is 1.25 and Windows XP is 1.5.

I saw this for the first time last week also. The computer was resuming from going to sleep several times, so I figured it was just resume wonkiness. I did just reinstall windows though, so maybe it's Windows Update related. It did have some updates to install.

Windows 7 recommended page file is DON'T change it, leave it as it is.

I tried that with my win7 64, min 12 gig and max 12 gig and my windows HATED that setting, win7 refused to work properly due to it and I had to go back to windows decides or setting a different value.

In the end, I just went back to letting it decide what it wants to do as I have no need to try and piss about with it like I used to do with win xp.

Application memory leak. Don't leave shit running if you don't need it.

/thread

luckily win 7 is smarter than xp when it comes to that.
you can run the system speed test tool and it will auto adjust stuff for you. (at least when you have a SSD)

I just upped my memory to 16GB and it took 16GB from my hard drive.
I had 52GB free when I shut down, and now I have 36GB Free.

btw, check your Event Viewer and see if you have any srv Errors listed. Mine started on Dec 5th and I have a ton of those errors in my Event Log.

I think I see the problem...at least why you ran out of memory.

Paged Pool was taking up 28GB (!!).

That more than likely indicates a driver problem. I recommend that you grab a copy of RAMMap from sysinternals. Keep it somewhere handy and run it when you see the low memory condition again. Post up some screenshots and let me know what you see.

Have you done any driver updates or anything lately? It's also possible that autocad could install some sort of driver that may have a leak in it.

I would change your pagefile back to where it was and leave it there. Adding more page file won't really stop this from happening if it's actually a driver memory leak.

Anyway, hope that helps. Let me know what you find.
