Why does dllhost.exe Com surrogate consumes memory untill crash

This appears to be a common issue for those people using Sony 3D Bloggie cameras.  Windows updates are the likely cause.  My machine is always looking for something that it can't find until it crashes due to the dllhost sucking memory.

I don't think that this is helping Sony, camera manufactures, content providers, or the 3D TV makers that predict a bright future for 3D TV yet do nothing to support it, and complain that their sales did not meet their unfounded predictions for their unsupported products.  And Microsoft will let us figure this out for them or simply pretend that is is not their problem or an issue that they created.

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.

Have scoured the net and found scores of solutions suggesting - running the system file checker, registry cleaners, modifying the startup and so on...these do not solve the problem. 

As noticed by other users and on other sites, the problem crops up after running Hi-Def multimedia files typically .mp4 file extension in my case afterplaying such hi-def files usingbuilt-in Windows Media Player 10

**Also I am not sure if this has relevance but I noticed this happening after I had updated to IE10 recently.**Till such time IE 8 was in and had not noticed such a problem

1 quick fixthat I use to resolve the problem in Win7 is as follows

Open Task Manager -> Go To Process Tab, Locate the "dllHost.exe" entry . Right click on it, and use "End Process Tree",  this will kill the process that spawned the dllhost.exe and restore the system to normal state. Open the Task Manager again and check for the entry it does not list again till the next time a hi def file is played using Windows Media Player

This needs to be done whenever the dllhost.exe is found to cause high Memory usage.

Please note that using the End Process  option will NOT work as the dllHost.exe will be re-spawned.

Problem is seen from Vista time frame, has propagated to Win7 versions as well.

Although there are threads within Microsoft communities that a Specific Windows update is the cause of the problem(http://answers.microsoft.com/en-us/windows/forum/windows_7-pictures/why-is-dllhostexe-crashing-while-trying-to-create/940e114b-e87e-45ff-8d33-0a5abf15bca9)..I still what might have caused the problem would be used to address the problem. Hopefully Microsoft might already have solution for this problem and same could be received via Windows updates.

I stumbled upon this Kb article while doing something else, but what caught my eye, was what this hotfix was intended for. I haven't experienced the issue that is being discussed here, so I cant really speak to it but I found this article intriguing enough to post the link here for those of you that know what is happening, to see if it might be related.

Certain JPEG images cannot be displayed after installing Update KB2670838

http://support.microsoft.com/kb/2836502

Take a look and find out if this is what is actually causing the issue.

We are many with this problem. Microsoft should do something about it.

Hope someone can help

Sooo, MS Update has now kb2834140 which is supposed to fix kb2670838. Sadly it does nothing for the thumbnail issue.

While testing, I had to reset the thumbnail cache with cleanmgr.exe, because the thumb in the cache was used and dllhost was not leaking, because the 3D-mp4 thumb was already created.

As usually, renaming and killing dllhost to complete the renaming worked to stop the leaking.

I suspect, there are more possible causes for a broken thumbnail system. If dllhost only leaks memory if it tries to create a thumbnail for a mp4 with h.264 content of a 3D video (a side by side trailer in my case) it seems to be caused by kb2670838 which is a prerequisite for or included in IE10.
