One of my web servers just started hanging.  It is probably related to a rule I put in.  However, I am unsure.  When I look at the Task Manager, I see a bunch of vsjitdebugger processes and the processors running at full capacity.  In the event log, I found this error over and over:

Thread information:
    Thread ID: 1
    Thread account name: NT AUTHORITY\NETWORK SERVICE
    Is impersonating: False
    Stack trace:    at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)
   at System.IO.FileInfo.get_Length()
   at Snapsis.HttpModules.PageBlaster.Utils.CleanFolders(String path, TimeSpan cleanupInterval, Boolean recurse)
   at Snapsis.HttpModules.PageBlaster.Utils.CleanFolders(String path, TimeSpan cleanupInterval, Boolean recurse)

   at Snapsis.HttpModules.PageBlaster.PageBlasterModule.Init(HttpApplication app)
   at System.Web.HttpApplication.InitModulesCommon()
   at System.Web.HttpApplication.InitInternal(HttpContext context, HttpApplicationState state, MethodInfo[] handlers)
   at System.Web.HttpApplicationFactory.GetNormalApplicationInstance(HttpContext context)
   at System.Web.HttpApplicationFactory.GetApplicationInstance(HttpContext context)
   at System.Web.HttpRuntime.ProcessRequestInternal(HttpWorkerRequest wr)

What is causing this?

The CleanFolders utility executes at startup of the application and deletes any stale cache files on the disk.
If this error is happening a lot then the application is probably restarting a lot.
The actual error may be from an empty file, although I think that should still work without errors though.

If you delete all folders and files in the PageBlaster cache folder then the error should go away.
