Why does dllhost.exe Com surrogate consumes memory untill crash

While Your information is great for finding spyware or virus problems.

I did as you said and found no problems.

My problem is with generating thumb nails for 3D video files with extension .MP4.

2D *.MP4 files are working fine, dllhost.exe-com surrogate comes up consumes about 3k of memory then goes away and the thumb nail is done.

As for the 3D *.MP4 video files dllhost.exe-com surrogate comes up and keeps consuming memory about 14GB then My system freezes and crash.

I have a total of 16GB memory installed.

Fix

"MS are aware of problems with certain chipset/driver combinations and the KB2670838 update

They are also aware of problems with the IE10 install

They are working on both issues, and will update as and when they are satisfied that they have solved the problems.

The recommendation in the meantime is that if the update doesn't install first time, make sure it's uninstalled, and then hide it - Windows Update will unhide it when it is updated."

So Uninstall IE10 and KB2670838 update, hide them from auto updating when thy pop back up to be updated the problem should be fixed.

Proof that MS knows that IE10 has problems on some hardware platforms is here.

Why does dllhost.exe  Com surrogate consumes memory untill crash.

It happens when I highlight or view a folder containing video files, Even if I close the folder or select a different folder the memory keeps getting consumed.

It seems to happen mostly with 3D Video files but it has done the same with 2D files.

So it seems to be a problem with the windows thumb nail system dealing with these files.

By the way trying to delete or move the file or folder while the Com Surrogate is consuming memory Delete can not complete the task.

What I have been doing is finding offending file selecting Delete, then go to task manager stopping Com Surrogate, then the file will delete.

Try running system file checker through cmd.

It is recommended to perform scan using:

http://www.malwarebytes.org/

Make sure your system is clean first. use CCleaner to get rid of junk files: http://www.piriform.com/ccleaner/download

Perform scan for spyware also using superantispyware http://www.superantispyware.com/

You could also use this one http://www.emsisoft.com/en/software/eek/

Also scan for viruses using your antivirus program and make sure it is uptodate. if you don't have one then I recommend Avast FREE antivirus.

It is recommended to perform all scans in Safe made with networking so that you can use internet to update your programs.

If above did not fix the problem then:

Go to msconfig (type in search box in startmenu or run in xp then press enter) then prepare your PC for clean boot by disabling all start up items and none windows services then restart your computer. See if it make a difference? if it did then you have to find out which ones caused the problem.

Also make sure your windows is up to date and drivers are working properly (Check device manger for danger signs) and they are up to date too. Also check hidden drivers for danger sign by showing hidden devices through view menu in device manger.

Uninstall programs you don't use or you have recently installed that might have caused the problem.

Uninstall toolbars, any registry cleaners or any other unused or rarely used third party programs.

You can replace task manager with Process Explorer.  When the dllhost.exe starts to chew up your memory, you can mouse over the dllhost.exe that is using up all the memory (there will be two of them), when you mouse over it you see the process that is running in dllhost's shell.  It is thumbcache.dll  So you see that is why all you are seeing the with or related to a 3D clip (I have the issue and it is a Toshiba 3d HD Camcorder Z-100 camera files I am editing with Sony Vegas, or moving with Windows Explorer.  I have Win 7 Ultimate 64 for my OS.  I am using Mpeg-4 .mp4 3d files.  I just ran chdsk on my PC and all is well... I suspect a bad Codec with a memory leak.  Now to figure out what codec is used to look an mp4 3d files... oh the fun... for now I just leave the task manager up and kill the dllhost as often as I need to... things seem to be fine with it killed LOL  Help Microsoft????

That's really interesting - I am having this same problem with all 3 of my computers - and as a 3D filmmaker they all have 3D .mp4 files on them.

I am running Windows 7 64 bit Home Premium on two of them, and Windows 7 Pro on the third PC.

It cannot be that all have become infected at the same time, and I've seldom had any infections over 15 years on computers.

I think that perhaps the last Windows System update has done something that is causing this.

Did you run the System File Checker? If you did what was the results?

Did you try clean boot ? Did it make a difference?

Also make sure that all your drivers are working properly as I said before.

Consider checking your disc for error. See if that helps?

Consider resetting your folder settings from control panel > Appearance and Personalization then folder options then restore default settings for all tabs there Or try reset folders button in view tab then apply then ok.

Consider updating or re installing your media player if possible.

Consider disabling thumbnails, will it still crash without thumbnails enabled?
