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!

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.
