I have a Web Server running IIS 5 or 6 on Windows 2K and Windows 2003 Server
that is experiencing strange shutdown problems. We are using ASP.NET v1.1
and our application is written in VB.NET
Here's the scenario:
1. .NET Windows Client on a remote machine makes a web service call to
update tables on a Web Server running SQL Server 2000.
2. The Update is updating about 1000 - 3000 records doing simple update
statements like "Update transactions Set UpdateTime = '08/12/2003 04:30:00
PM' "
3. The SqlClient code is receiving the error message below:
Timeout expired. The timeout period elapsed prior to completion of the
operation or the server is not responding.
The statement has been terminated. at
System.Data.SqlClient.SqlConnection.OnError(SqlException exception,
TdsParserState state)

exception, TdsParserState state)

HorizonBoss.MealPayLive.BusinessObjects.Patrons.Patron.UpdateLatestBalanceIn
formation( DataSet currentBalances ): Timeout expired. The timeout period
elapsed prior to completion of the operation or the server is not
responding.
The statement has been terminated.
4. I have all my code wrapped in Try/Catch blocks so I see where I catch the
Exception and write this out to a log file.
5. I have code in the Application_End section of the Global.asax and I see
where a different Thread ID comes along and ends my running application.
