Error: no more threads can be created in the system

Question

_{Wednesday, February 18, 2009 7:22 PM}

On trying to open the IDE using Run As administrator checked in the shortcut options, I've suddenly started getting the error:

"c:\program files\microsoft visual studio 9.0\common7\ide\Devenv.exe

No more threads can be created in the system"

I'm running Vista Ultimate and VS 2008 SP1 is installed and has been running fine up until yesterday.

If I disable Run As Administrator in the shortcut options, the IDE runs fine

Anyone else experiencing this?

Ben

Some additional info -- usually when you run out of thread space, an app is misbehaving; either it's spinning off too many threads or (usually) not releasing old ones properly.  You can check the number of threads currently running in Task Manager under the Performance tab in the System section.

Does this error occur right after restarting Windows, or only after it's been running awhile?  Try restarting Windows, minimizing the number of other programs that are running (including services and applets) and see if the problem persists.  It might take a process of elimination to pinpoint which program is causing the problem.

BTW, here an interesting blog post about threads in Windows to help you understand them better.

HTH,
