A Process Serving Application Pool 'defaultapppool' Suffered A Fatal Communication Error
#1 Our production server has recently started experiencing AppPool crashes. These seem to occur sporadically. sometimes three times a day, sometimes not for a couple of days. The error manifests itself to the client as "Service Unavailable". In the system event log we see the following:A process serving application pool ‘DefaultAppPool' suffered a

fatal communication error with the World Wide Web Publishing Service With error number: 8007006d At the same time (but not always) we see this error in the Application Log "Faulting application w3wp.exe, version 6.0.3790.0, faulting module kernel32.dll, version 5.2.3790.0, fault address 0x000249d3" The application does usually start working again after anywhere between 2 and 15 minutes (although no worker process restarts or recycles appear in our perf logs). This problems seems to have started occuring following the latest MS patches being applied to our server. It may just be a coincidence though. We are running Windows Server 2003 Standard. We are about to apply SP1 in an attempt to solve this problem, but I wanted to find out if anyone else has had this problem and what the solution was. I have seen several similarish posts but nothing concrete as a solution. I have seen this article (http://support.microsoft.com/Default.aspx?id=885654) but it doesn't quite match our situation as
★★★★★★★★★★★★★★★ Christopher T. HaunNovember 12, 201313 0 0 0   Summary  When a user-mode process (such as w3wp.exe, owstimer.exe, iexplore.exe, or any .exe) is crashing (such that the process disappears unexpectedly from task manager and reappears soon debug diagnostics tool after with a different PID number), arguably the best way to begin to determine the
Iis Dump File Location
root cause of the crash is to catch a crash dump as that process is crashing. This blog offers two ways to trigger app pool crashing iis 7 the crash dump and suggests a way to begin interpreting the dump.  The Choice between DebugDiag and WER   I highly recommend the use of DebugDiag as the tool to use to automatically trigger a crash https://blogs.msdn.microsoft.com/david.wang/2005/08/29/howto-understand-and-diagnose-an-application-pool-crash/ dump as the process crashes and as the tool to begin analyzing the crash dump. The tool is simply the most flexible and customizable way to get simple crash dumps and advanced crash dumps. But since I'm taking here about simple crash dumps, and since it's not uncommon for the change management process to move too slowly, and since some IT groups have very restrictive tool installation approval process for their servers, sometimes DebugDiag cannot be https://blogs.msdn.microsoft.com/chaun/2013/11/12/steps-to-catch-a-simple-crash-dump-of-a-crashing-process/ installed on a server where a process is crashing, I also am going to offer steps here to use Windows Error Reporting (WER) to automatically trigger the crash dump. Often WER is adequate to get the crash dump. So I'll start with WER. But if you have permission to install DebugDiag on your server, feel free to skip the WER steps.  How to Set up WER for a Crash Dump  WER is already there! WER is already part of your operating system (in Win2008 and higher) and needs only to be configured.  You'll need to add a registry key. As an example, to catch a total of two crash dumps of a crashing w3wp.exe process, you could use copy the following text into notepad, save it, and rename it to something like W3wpcrashdumps-to-C.reg. Windows Registry Editor Version 5.00   [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Windows Error Reporting\LocalDumps\w3wp.exe] "DumpFolder"=hex(2):63,00,3a,00,5c,00,64,00,75,00,6d,00,70,00,73,00,00,00 "DumpCount"=dword:00000002 "DumpType"=dword:00000002   This will make a total of 2 full user dumps (not mini-dumps but full dumps) and write the dumps to C:\dumps. In the registry it will look like this:   But you may not want to write the dumps to the system partition. You can send it to another drive with a few GB of free space instead. So, as an example, to send the dumps to the D:\ drive you could use something

On previous versions of windows the error message is, I believe, caused by hard-to-see code errors. I have a sample VB6 project that can generate a similar windows error and crash the vb ide, for example, and it's caused by a problem in my code. ====== Doug G ====== I've never been able to appreciate the sublime arrogance of folks who feel they were put on earth just to save other folks from themselves .." - Donald Hamilton Faq Reply With Quote January 27th, 2006,07:20 PM #3 No Profile Picture glorioso View Profile View Forum Posts Registered User Devshed Newbie (0 - 499 posts) Join Date Jan 2006 Posts 2 Rep Power 0 Doug, Do you know is there is any tool out there that would help me find the problem in the code? or do you any other way of finding what the problem is? thank you Faq Reply With Quote May 9th, 2006,02:26 AM #4 No Profile Picture etcefala View Profile View Forum Posts Registered

Two machines, identical systems on them, identical programs (mostly). One has Visual Studio installed, one has ... uhmm, something else. Sometimes when I try to install applications from let's say a CD, Visual Studio's Just-In-Time Debugger pops up, reports an "unhandled win32 exception in ..." and asks whether I want to debug using "New instance of Microsoft VIsual Studio 2010". If I choose Yes, it runs VS, if I choose No it closes the thing, and I'm back in Windows Explorer. Which would be ok, except I know the application is perfectly all right, and this way I cannot install it (in this latest cast it was the client from my bank for internet banking and paying bills and such). So, how do I get rid of that thing (just-in-time debugger)? I don't want to uninstall VS since I'm using it daily, of course. Edit 1 :: I tried disabling Just-In-Time debugging in VS's Tools/Options/Debugging/Just-In-Time, then unchecking all three checkmarks, but that just gave another error when trying to run the executable installation program. An unhandled win32 exception occurred in autorun.exe [some number]. Just-In-Time debugging this exception failed with the following error: No installed debugger has Just-In-Time debugging enabled. In Visual Studio, Just-In-Time debugging can be enabled from ... Check the documentation index for 'Just-in-time debugging, errors' for more information. Very informative :/ Edit 2 :: The application runs fine on the other machine that doesn't have VS installed. To a large extent software on both machines is the same, with just some minor differences (systems installed from image). Minor differences: notepad2, ++, git, ... some small stuf
