I really appreciate your help. I found something that may be important. I've been running Insomnia a free app to prevent the computer from going to sleep. That may have prevented the problem.

I tried this because I noticed that putting the computer to sleep and waking it up provoked a memory leak. Anyway, it's been working for a couple of days now and that could be unusual.

In most situations it is preferable to configure the computer to produce a kernel memory dump when system failure occurs. A complete memory dump is a very large file to handle so it is more practical to work with Kernel memory dumps when trying to resolve blue screen errors. Please change your dump files settings to produce a Kernel memory dump. Under System failure check the boxes before Write an event to the system log and Automatically restart. Change the Write debugging information option using the scroll to the right to Kernel memory dump.

Restart your computer to apply the changes. I have had continued success with Insomnia. By not putting my computer to sleep, I have so far avoided the problem. But that, for me, would be a bad solution. I had given view only rights. I updated that to edit. You should change your systems settings to create a small memory DMP. Determining Whether a Leak Exists describes a technique you can use if you are not sure whether there is a memory leak on your system. Finding a Kernel-Mode Memory Leak describes how to find a leak that is caused by a kernel-mode driver or component.

Finding a User-Mode Memory Leak describes how to find a leak that is caused by a user-mode driver or application.

Skip to main content. That also finished fine. From Win 7's beta to the version currently available right now, this is still a problem; a problem that Vista never had. Office Office Exchange Server.

I actually have two machines running windows 7 release candidate x64 and the I noticed the problem on both. The problem is easiest to duplicate if you run chkdsk on a drive other than your OS drive so you can actually have task manager open while it runs as opposed to running after a reboot , and if you run a check that will take a long time.

I would be interested to see if anyone else can duplicate this. Tuesday, June 2, PM. Monday, May 10, PM. Hmm, too bad I didn't notice this during the beta so I could push the "submit feedback" button.

This seems like a pretty serious problem, I wonder if there is a way to report it to Microsoft. I wonder if it could be driver related? You're right there, they probably want to fix this one! Im using an intel chipset so not an AMD only problem.

That aside Could chkdsk possibly be trying to load all the files on the disk into memory and then failing to unload them? The memory usage hits its peak once stage 4 completes, and it does not increase at all during stage 5. Wednesday, June 3, AM. What happens when other programs are using a lot of memory? In other words if the computer is just running chkdsk it would make sense for it to grab as much RAM as it can to get the job done quickly.

To find out what's really happening you'd have to run a very large series of different tests. Some with only chdsk running. Some with a lot of programs running at the same time. Some with various programs starting and ending while chkdsk is running.

It may be that chkdsk is optimized to use as much memory as possible without impacting system performance. Secondly in vista memory usage is really minimal. I thought the behaviour might be by design at first too, but I don't think it is because: 1.

Also this is how I discovered the behaviour initially I used to be able to run 4 instances of chkdsk at the same time on 4 hard drives since chkdsk is so easy on system resources I have a screenshot of task manager where the 4 instances are using 1. Once system memory gets full like this even chkdsk itself seems to get slower, although by this time it is usually on stage 4 where it is hard to tell.

Lately I've been wondering if I could copy the chkdsk. Would I have to copy autochk. Wednesday, June 3, PM. For anyone who is wondering if the above is possible, the answer is no. I copied chkdsk. I guess anyone who wants to run chkdsk in Win7 is going to have to wait for Microsoft to fix this first hopefully they know about it.

Sunday, June 7, PM. Any info about this? Is it present in RTM? I have 8GB of ram and page file turned off. This is definitely not by design ;. Wednesday, July 22, AM. However, the boot time scan is hanging at 1 second on the countdown and the keyboard is non-responsive. Anyone else have an issue like this? It took me a couple of reboots to get past it by typing on the keyboard right away. Saturday, August 22, PM. Saturday, September 26, PM. Not a memory leak.

It is chkdsk getting as much memory as it can to start the scan and keep it somewhat fast. A small workaround that I have found works is to start up a Virtual Machine, and let it acquire its normal amount of memory. Monday, November 23, AM. I've had the 1-second countdown problem as well. It's been extremely frustrating. I finally found that Microsoft released a hotfix for it about a week ago. It'll e-mail you a link to download the hotfix with a unique password, which you have to insert when extracting, after which everything will be solved when you execute the extracted file!

Hope this helps to solve this problem. Proposed as answer by robotsrock Thursday, November 26, AM. Thursday, November 26, AM. Unfortunately it seems they're not planning to further address the memory consumption issue. I suggest you consider the fact that we users usually have many activities underway in our computer. Surely checking and fixing a hard disk is important and we would the process to complete as fast as possible.

However, not in a way that degrades overall system performance so severly that affects our ability to be productive in other tasks while a disk is being checked. I hope you'll consider adding some switch to specify what percentage of system resources should be allocated for the chkdsk process, or perhaps a way for chkdsk to release some memory when not being the active window or when overall memory utilization is over some threshold.

Robotsrock, did the hotfix change anything about memory allocated to the chkdsk process? Thursday, November 26, PM. I'm not sure how this affects memory allocation.

According to the article, computers with infrared devices seem to be more likely to incur this problem. I had a HP dv7t with an infrared receiver that always used to pause on the countdown at 1-second and then totally freeze. Then chkdsk would attempt to re-run every time the computer booted up until disabled from the command prompt, causing a lot of problems as I couldn't get to the login page! That hotfix solved the problem. Hope this helps.

Saturday, November 28, AM. Sunday, November 29, AM. Parameters seems not make the difference as well, and in terms of speed - it does not differ in any way from a parallel installed Vista x64 Ultimate Well, maybe there is a fix or tip on how to handle this, since it is really annoying.

Doing something right does mean noone takes notice. Wednesday, March 17, PM. It sure would be nice to get an indication from Microsoft on whether this is intended behavior; perhaps the increased memory usage is an enhancement to CHKDSK to make it more capable or robust in the new OS We DO have other uses for the computer resources e.

Thursday, March 18, PM. Monday, April 5, PM. Interesting that the blog article linked-to above yields this insight from Microsoft: The file system team immediately began to look into the issue. Tuesday, April 6, PM. Hi, Noel. Thanks for your reply. Hope you consider adding some switch to limit resources the command allocates. Best regards, Mario. Wednesday, April 7, AM. Wednesday, April 7, PM. I'm sorry if my wording led to think you work for MS.

Regards, Mario. Sunday, April 11, PM. Very good point about it being able to run in 2 GB. Monday, April 12, PM. Noel - It's not you Sorry if I made it sound like you're the one I was skewering. Sunday, April 25, PM. If this is the biggest problem you are facing, you live a charmed life. Sunday, June 27, AM. Glad to see others share my point. Sunday, June 27, PM.

I suggest using the reboot chkdsk mode so that maximum resources are available for it. Monday, September 27, PM. Friday, November 12, PM. Suffering with this problem also. Sunday, July 17, PM.

Monday, July 18, AM. Monday, July 18, PM. The workaround is to disable Indexing. Event viewer says: "Windows successfully diagnosed a low virtual memory condition. Yes Microsoft, very well designed, indeed. Microsoft, can you hire me as a designer, I think I can do better : In conclusion, I see that no fixes are provided.

Thursday, July 28, PM. Friday, July 29, AM. Sorry to reply to such an old topic but I might have something to lend to this as well. My system has a lot of memory 16 GB and chkdsk ran it the whole way up to Perhaps chkdsk is designed to use memory until there's only a certain percentage available?

I'm not sure how this would affect performance but it was processing files much faster than my other computers my CPU is also much faster, so my test would have to be refined to say for sure. Thursday, August 25, PM. Thursday, September 8, PM.

This is not a bug, this is by design behavior. Then it's a flawed design. If I want chkdsk to eat up all my system memory, there should be an option to run it in "exclusive mode" or something, but by default it should run exactly as it does in Vista.
