Application Error Faulting Application W3wp.exe
or being automatically shut down after a few application errors, then you have a major problem on your hands. In my case the symptom was A process serving the application pool suffered a fatal communication error with the Windows Process Activation Service, in my system logs. If you have each website running in its own application pool then you know which website is going down, but the errors being displayed give you no hints as to the cause. I recently had a website that was randomly going down. Sometimes it would go down every few days, and other times it would only crash once a month. So I finally did some digging for the cause, and found it. If you don't know where to start in debugging your crashed application pools, this might help.Why Does W3WP.exe Crash?In my experience crashing happens for only a few reasons. The first is an unhandled Exception which was serious enough to crash the Application Pool which is rare but does happen. The second is a recursive function or a set of functions that continue to pass the ball to one another with nothing stopping them. In my case this was the case. I had two functions that got caught in a loop and continued to run out of control until the server bottle necked due to CPU or memory usage.How do you know when your Application Pool Crashed?Easy check your event viewer Application Logs under Windows LogsThe Red Exclamation points are telling you there was an Application ErrorBut the details of the error don't help us very much.

After the dump is created, you can use DebugDiag to analyze the dump for you. Although with that particular exception, you probably need to use WinDbg+SOS. Some of the more relevant information: "For stack overflows as most of you probably know, the most common reason is that we are in some type of recursive loop, so what we really would like to know here is what is on this stack… The reason why it is showing up with just addresses and not method names, is because debug diag doesn’t understand .net so we’ll have to bring the dump to windbg to analyze it and check out the .net stack. "In windbg we can then load up sos (.loadby sos mscorwks) and run !clrstack on the active stack to get the callstack." (If you are running .NET 4, the command to load sos is: .loadby sos clr) Ultimately, what you are looking fo
