Q:

What does this Windows 2008 Debug output mean

I have a Windows 2008 R2 Virtual production machine, with VMWare tools installed.  I have installed my .NET 4 windows service on the machine which does 10 to 20 HttpWebRequests every minute.  I was looking at DebugView, and I see the following log.  Once that kind of log shows up in debugview, my app stops working.  It's still in memory without any exceptions logged ( I have enough logging in place).  But, it's doing nothing as far as I can see. 
If anybody can interpret or guess what's this saying that will be beneficial.  Only part I understand here is Wsk means WinSock Kernel!

A:

WSK log is jut information.  There is not error reproted by it.  All the IRP are successfully completed.  KTM(Kerne Transaction Manager) log says that it rolled back two transaction, I didn't get what transaction, becasue it may be your app specific.
