Our IIS site has its own app pool which is set to run under http error 503 the application pool identity. Almost immediately after startup when first accessing a page the app pool will stop. I can restart the app pool and attempt to access a page and it will stop again, sometimes partially loading a page. The same is also true for accessing static content like CSS - it might load once, but a second attempt will yield a "Service Unavailable 503" response. Nothing is being written to the application event log and the httperr.log files show the following: 2015-07-01 09:04:36 10.7.40.217 58318 195.47.225.106 80 HTTP/1.1 GET /Account/Login 503 14 AppOffline ourapp.ourdomain.com We're tried a few things mentioned elsewhere like ensuring the loaduserprofile option is disabled for the app pool and disabling rapidFailProtection. Other users seem to report seeing errors logged to the application event log, but we're not seeing anything similar. Could these be being written elsewhere? iis-7 windows-server-2012-r2 application-pools windows-server-core share|improve this question asked Jul 1 '15 at 9:18 Rob Bell 1231211 Have you enabled Failed Request Tracing, you might get something logged there: iis.net/search?searchterm=failed%20request%20tracing Also check your httperr log files in:
may have run into an Error 503 Service Unavailable. Actually, there may be 4 reasons for this error. We will introduce them in detail and help you to resolve this issue accordingly in the following parts. Now, please go on reading. 1. .NET CLR Version & Managed Pipeline Mode Once your .NET CLR version is not set correct, your website couldn't work properly. Some web-hosting providers only provide 1 dedicated application pool for each hosting account in a shared Windows server. Thus, when you run more than 1 website with different .NET framework hosted with one account, they will get conflicted with each other. For example, you can successfully run a website named A.com when you use .NET 2.0. However, when you try running another website named B.com with .NET 4.0, it's very likely for you to run into 503 error at A.com. This is because the operation of B.com updated the shared application pool to .NET CLR Version 4.0. The same logic goes for Managed Pipeline Mode, which has 2 types: Integrated and Classic. By using local or remote IIS management, you are able to open your IIS Manager and find application pool. Then click Advance Settings. Here is what you can see as it shows: If you're not allowed remote International Information Services management, you should go to your WebSitePanel, find "Extensions" in "Your Site" part and pick the correct ASP.NET pipeline. 2. Enable 32-Bit Applications This is another possible reason for Error 503, which can be found in the above placed screenshots. Here are the 3 most common reasons for this Error 503 caused by Application Pool Bit Mode setting. The Classic ASP site can only work in an environment with 32-bit. You're likely to confront this error if you: run a .NET site in an environment with 64-bit and it is hosted with a Classic ASP site or run a site with 64-bit set default by us. Your .NET site is specifically compiled with 32-bit or 64-bit environment, but it is hosted with another mode. Your .NET site requires library that run with 32-bit or 64-bit environment, but it doesn't operate that way. 3. Application_Error A code bug may cause a site's application pool crashed, thus resulting to Error 503. If you can change the source code, you'd better add the following logging function to Application_Error of Global.asax.cs. As thus, you're able to find some clues in the log file if you confront this issue next time. Read the following code snippet. protected void Application_Error(object sender, EventArgs e) { string logFilePath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "logs.txt"); using (StreamWriter sw = new StreamWriter(logFilePath, true, System.Text.Enc
