group:IIS/SQL Crashing
iis security:
Hi we run a website based on htm/html pages, asp scripts and an SQL backend.
Before we had a problem and were having a lot of events in the sys event log and after some time, if i try to access the website i would have an error "Service Unavailable" Then i turned the web server to run in "Isolation Mode" though everysome time it seems that the IIS stop communicating with the SQL server. In fact the whole pages load up but the SQL driven data won't show up :\ The only even we are finding on the web server is this: Event Type: Warning Event Source: W3SVC-WP Event Category: None Event ID: 2237 Date: 1/28/2004 Time: 3:30:03 PM User: N/A Computer: S42910 Description: Out of process application '/LM/W3SVC/179685904/Root' terminated unexpectedly. For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp. Also i found other events that say the the IIS services has terminated unexpetadly and they are being restarted automatically. Any help please would be really appriciated cause i am getting mad. Regards, Robert Abela
Hi desmond,
Since it is a production server we merely have chance to check all these things unfrotunately :\ Though we do not use any third party dll's etc, though do you think it can be some bad code from the webdevelopers when communicating with SQL?

Hi Robert,
Based on event log, there is probably a fatal error in your application that cause the worker process to crashed. There are many possible reasons to the cause of an application crash such as memory access violation or stack corruption. Sometimes it may be due to some miscompiled dll or third-party drivers that causes the problem. The best way to determine is to perform user-mode debug of the worker process memory space at the time of the crash. You may go to Microsoft website at http://www.microsoft.com/whdc/ddk/debugging/default.mspx to download the tool and there are also instructions available on how to go about setting up the debugger and attaching it to the IIS process to capture the dump when it crashes. However analysing the dump file requires quite a bit of knowledge on programming, assembly language, and OS internals, it can be pretty challenging to layman. Here are some link that you may find helpful: HOW TO: Use ADPlus to Troubleshoot "Hangs" and "Crashes" http://support.microsoft.com/?id=286350 http://www.microsoft.com/whdc/ddk/debugging/DBG-KB.mspx Have fun!
