So, there is a horribly written site that I occasionally help out with that was originally written in classic ASP. It was then "ported" to ASP.NET by moving the global variables to the code behind and leaving the rest of the code in the aspx...Its a huge mess. On some pages, an occasional race condition seems to be triggered that cause...
When I attempt to update the code on a IIS webserver by replacing the old code with my new code, I receive 503 Service Unavailable replys when attempting to access any of the replaced pages on the server. What is the cause of this failure and what steps can I take to correct such errors? Thanks. ...
I would like to configure a webservice so that once the accept queue is full the service returns 503. Currently, these requests seem to just time out. I did set paramters like maxThreads and acceptQueuesize (as described here: http://www.restlet.org/documentation/1.1/ext/com/noelios/restlet/ext/jetty/JettyServerHelper). But the servic...
I'm running into some performance issues using a generic handler that implements IHttpAsyncHandler. At its simplest, the handler receives a GET request, and 20 seconds later ends the response after writing '< timeout / >' to the response. When hammering the .ashx with 10000-20000 simultaneous requests, it fails with 503 server unavailab...
I have inherited an application (internal to my company) that uses javascript running in Internet Explorer which makes Ajax calls to a Struts-based application running in WebLogic Server v10. Certain server-side operations in the system are taking longer than 3 minutes. Users consistently noticed that the Ajax call returns 503 error at...

I looked in the Event logs and discovered that: A process serving application pool 'Classic .NET AppPool' suffered a fatal communication error with the Wi...

I need to send a Customized Error page for 503 Errors produced by my asp.net website. I have tried to simulate the condition by switching off the application pool (doesn't work) and by flooding my application with requests. Even though IIS sends me the default 503 error page, and even though I have tried setting a Custom URL in IIS and ...
My knowledge of how processes are handled by the ASP.Net worker process is woefully inadequate. I'm hoping some of the experts out there can fill me in. If I crash the worker process with a System.OutOfMemoryException, what would the user experience be for other users who were being served by the same process? Would they get a blank scr...
I just installed .net 4 on my server 2008 and I keep getting Service Unavailable HTTP Error 503. The service is unavailable. messages from any application I try to run as .net 4. The application pool keeps stopping. Event view shows: "The worker process failed to pre-load .Net Runtime version v4.0.30319." ...
(This is a cross-post from servefault. I'm posting it here because no one answered my post there, and I feel that this sort of hits an awkward space half-way between both stackoverflow and serverfault.) I have modified the example project included with Solr for my needs (removing things like the example stopwords and defining my own sch...
I have a multisite drupal installation with domain access module. Off late, I have started getting this warning 'need to build access permission'. Also, I went tried rebuild the access permission, I get 'An HTTP error 503 occurred. /batch?id=24&op=do' The solutions suggest that I disable the modules and rebuild the content access perm...
