Timeout Or Server Busy Error During Backup......WHY?
Mar 1, 2007
I have the standard version of SQL2005 and have a backup maintenance plan that runs every Sunday consisting of the following steps.
1. Check Database Integrity
2. Rebuild Index
3. Back Up Database (Full)
The backup itself works fine, but sometimes during the backup I am unable to insert new records into the database that I am backing up.
I believe from all the documentation and other comments I have read that the database should always be available for inserts or updates even during the backup operation. The error I receive from VB.NET application is:
System.Data.SqlClient.SqlException: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection)
at System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection)
at System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning(TdsParserStateObject stateObj)
at System.Data.SqlClient.TdsParser.Run(RunBehavior runBehavior, SqlCommand cmdHandler, SqlDataReader dataStream, BulkCopySimpleResultSet bulkCopyHandler, TdsParserStateObject stateObj)
at System.Data.SqlClient.SqlCommand.RunExecuteNonQueryTds(String methodName, Boolean async)
at System.Data.SqlClient.SqlCommand.InternalExecuteNonQuery(DbAsyncResult result, String methodName, Boolean sendToPipe)
at System.Data.SqlClient.SqlCommand.ExecuteNonQuery()
The problem only occurs during a full backup, not differentials or tranaction log backups. Sometimes after catching the above error I can insert into another table, but at other times I am not able to insert into the desired or backup table and simply have to write the data to a file and insert it manually at a later time.
This problem does not consistently occur since a backup may take 10 minutes and during that period maybe 5 of 6 records are inserted correctly, but one will fail.
Why doesn't the database always allow inserts during the backup? It should, shouldn't it?
We have been bothered with this problem for a while. Usually I happens in the early moring. Later on after the error is gone on auser, the error never happens again on any user for the day. Is this a web Server problem or an aspx.vb coding error? Thanks,Jeffrey Server Error in '/SSSSS' Application.

I am getting this error when I try to back up the larger DB's on myserver. The smaller ones back up ok. Is there a parameter I can changeto increase this timeout? I have gone into ODBC, Query Analyzer, andSQL server properties and played around with some settings, but nothingseems to work.Any help is appreciated!Phil
Hi, I am running a stored procedure that collects some records from two tables do some calculations with those records and insert those calculation result in a temp. table. I am calling this stored procedure in my aspx page and then later select all the records from temp table and show it in a table. When I run this application on browser it give me Timeout expired error but whn I execute the stored procedure it runs properly but takes around 3:10 mins to execute in query analyzer. I did some google work and based on that I specified CommandTimeout = 300 for SP and Connection timeout=400 in web.config. But still it didnt worked. Sometimes it runs properly but sometimes its not. Where I am doing mistake? and Wht should i do to resolve this? Plz. help. Thanks in adv. Regards, Yogita

We use db maintenance plans for backup os sql server. We would like tosend an alert if the backup job runs for long time(over 3 hours). Howcould we achieve this using maintenance plan? Retry time would not helpin this situation. Any ideas?
Error: 0xC0202009 at Load SQL Deals, Insert SQL Deals [12494]: SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80004005. An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80004005 Description: "Connection is busy with results for another command".
Why isn't the connection manager managing this?
How can I trace the cause? The data flow component (insert SQL deals) is just a simple INSERT statment.
I am having multiple threads in my c program to execute same procedurewith differnt parameter values every time.I have created different functions to execute the same.However when SQLExecute is run on one of the thread it returns anerror saying[Microsoft][ODBC SQL Server Driver]Connection is busy with results foranother hstmtHow do I call the same stored procedure on different threads toexecute at the same time.
I have looked at other threads regarding errors similar to this, but I think mine is a bit different.
I am using SQL2005 Standard Edition and my application is coded with C# using ADO.Net. OLEDB connection is used. The error occurs when the application has only one thread accessing the database. It does not happen consistently, so it is very puzzling.
I am wondering if anyone could offer any tip to diagnose this.
I am working on a SSIS solution that has 4 packages. All 4 have run before and I have not modified any of them, however I keep getting the error message and it keeps locking up on one of my packages. Does anyone have any advice or a remedy for this?
Hi,I get this error from our web application every once in a while. " Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding". I email myself when an error occurs, and once every 2-3 days I get this timeout error emails, like 5-10 emails in a span of few minutes. Then it goes away. I have set the command timeout for 60 secs. It doesn't happen from the same stored procedure, actually I have seen it timeout from really simple 1 or 2 line stored procedures, which shouldn't normally take 1 sec. Its like sql server just shuts down for few minutes. We have some backups and maintenance jobs scheduled, but they run only after midnight. I have checked the application event viewer, there are no warnings or error messages for MSSQLSERVER. Can any one tell me how to check whats going on during that short timespan when timeout error occurs, and what causes it? I don't want to run sql profiler continuously for 2-3 days, I am afraid it will slow down the server more. Thanks.
We have several large government web sites that we help look after. We recently migrated one of them from SQL Server 2000 to 2005 and are having a problem with our nightly email job in that if it runs for more than an hour then after exactly 1 hour the email job gets a "Timeout expired" message back from SQL Server.
Our batch jobs do run on a different server and connect remotely to our SQL Server DB. I did change the connections - remote query timeout and increased it 10 fold, but this didn't make any difference. Is there any other parameter that may be causing the Timeout expired error after exactly 1 hour?
Coupleof my users receive a "timeout expired" error when using an ADP project application that connects to sql server. Others do not have this problem at all. What could be the issue? The queries that are being run are not large queries at all so they should not take more than 30 seconds to run.
I have a SQL server that runs a full backup on sunday and differential backups on every other day at midnight. There are also transaction log backups scheduled every hour on the half hour. I have a VB.NET service that accesses this database. During the time of the backup the service will occasionally throw execptions when attempting to open the connection. It is a the standard SQL timeout exception with different codes returned.
System.Data.SqlClient.SqlException: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
I don't get any timeout errors during the transaction log backups only the full and differential backups. There are no errors on the server stating that there was problem performing the backup. The timeout period is the default 30 seconds. The SQL server is running 2005 enterprise edition, and the service is on the same box as the SQL server, so there is no network traffic issues.
Hello, I am having above mentioned error while inserting records in database.This arises sometimes after 10 records or 20 records.I dont have any object such as hstmt. before this insert query ,there is another query where I get one colume value from another table. please can anybody tell me reason of this kind of error. Thanks in advance
I have found a similar problem in Google but that thread doesn't have any conclusion. So that I wish a new thread can help solve this problem ultimately.http://forums.asp.net/rss.aspx?ForumID=54&PostID=1600414Problem description:TableAdapter will raise timeout exception when I try to execute a SQL containing subquery and grouping. However, if the same SQL is executed in SQL Server Management Studio. The response time is always less than 1 second.Solution provided in previous link:Increase the timeout setting of the command - I think this is not the solution. As the default timeout should be 15 seconds, how could it get a timeout error if it execute a SQL supposed to be finished within a second?I have encountered similar problem before. However, I can't remember the exact detail. My solution for that moment seems to be using join instead of subquery in the SQL. Unluckily, this trick does not work this time.Please provide any other suggestion. Thanks in advance.
I am researching alternatives to a stored procedure that uses a linked server query that my ASP page uses to retrieve records to the page.
Should I:
Use replication (Data is constantly updated, so a snapshot won't do. Merge replication?)
Break up the stored procedure into subqueries?
Use a view on the remote server instead of the actual tables?
I am trying to reduce the amount of table scans, what is the best way to do this?
Here is the stored procedure I am trying to tune: (@startDate and @endDate are parameters passed from the web page):
CREATE PROCEDURE dbo.spELRMCcardXtionByDate @dcid nvarchar(255), @startDate datetime, @endDate datetime AS SELECT Store.[Str#], Store.[Dcid#], E.card_number, E.program_number , E.start_date, E.end_date, E.card_number, E.event_number , E.status, E.budget, E.scheduled_date, P.tx_time, P.purchase_amount , L.merchant_name FROM (Store INNER JOIN Event E ON Store.[DemoID#] = E.event_number) LEFT JOIN (Location L RIGHT JOIN POS_TX P ON L.location_number = P.location_number) ON E.event_number = P.event_number WHERE (((Store.[Dcid#])= @dcid)) AND E.scheduled_date BETWEEN @startDate AND @endDate ORDER BY Store.[Str#] GO
Any suggestions on my sp or anything else that can implement would be greatly appreciated.
we are working on a web application created in ASP & SQL 2000 environment. In the code , we have a single connectionstring to connect database. The application was running fine for the past 3 years, but all of a sudden we are getting "timeout expired" error only in someparts of the application but not on all database access. The code which raises this error is a bit large which need to look into table of 8k recs with more conditions. The same sql query took 1:01 minutes to execute in query qnqlyser. I changes the script timeout to 900secs, I herd we need to upgrade MDAC or we need to change connection timeout or we need to cahnge the code.
we cannot change the query, it is the most possible way we could get that.
My application is dependent on two databases one is on sql 2005 machine and other is on sql 2000 machine. A linked server is establish between these two using sql account which has appropriate rights on both server's databases.
application works fine but after some time it crashes and if i see error from sql profiler i get the error
OLE DB provider "SQLNCLI" for linked server "sql2000machine" returned message "Login timeout expired".
Few days back applciation was working absolutly fine, but i was trying to make linked sever through windows account, i dnt know wat has i changed during achiveing that setup that now application (linked server) is not working even with sql account.
Hey, From time to time i get this error "Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding." so I tried to change the connection string by adding thie following "Connect Timeout=200; pooling='true'; Max Pool Size=200" but still it is giving the same error! so why is this happening ? and what can I do! btw the timeout expired happens when a stored procedure is executed at the Fill method ! Thank you in advance Hiba
Hi All, I am facing a problem in SQL Server 2005 and the .NET Environment. I have an SP, which will return me the result within fraction of second when i execute it in SQL Server Management studio. But randomly (Frequently), its giving timeout when i execute it from .NET Envirnment. If i execute it at that same time in Management studio, i am not getting the error. But getting the Timeout when i execute it in the Server Explorere of VS 2005 or in the Application which uses it. Can any one figure out the solution.

Hi! I am having a problem with my windows app in VB.net. I am just trying to do a very simple select command to retrieve some data. I am using a hosting server with a VPN. When i click on the button it keeps giving me the error above. When I use server management express to do the same query it works fine and relatively fast. So I have tried setting the CommandTimeout to 120 but when it stops, the debugger shows that the value of the COmmandTimeout is 30, although it stops after about 15 secs. I am really lost and would need some help please! Find my code underneath.

I am getting this error on web server. My Appication is working fine on my Local Network where DB server and web server are on different machine. But getting TimeOut on web server. I tested the query on Query Analyzer it takes hardly 3 sec (Max) to execute. There is only Select query and total number of records are around 2100 which is not a big data. I have used Connect Timeout = 180 in connection string which is also not effective. please tell me how can I handle this exception.
We've been having timeout problems. In our development environment we have IIS and SQL Server 2005 both running on the same box. We use VWD or our dev server's IIS to run the apps. What happens is the database stops responding to our web applications and we continue to get the timeout error. I can still execute queries from Management Studio but all of the web apps all timeout. Then, the only was we can get the database to start responding again is if we restart the SQL Server service. Any ideas as to why the database would stop responding to all of the web apps but not Management Studio? It tends to happen a couple times a day when we are developing. Only the other developer and myself use the DEV environment.

Hi, I keep getting this error. I have a query that takes 47 seconds when I run it in SQL Server 2005. My connection string looks like this:connectionString="Server=server; Database=db; Pooling = true; Connect Timeout=60; Max Pool Size=300;I understand that Connect Timeout 60 = 60 minutes. Is there any other place where a timeout can be set in an ASP.NET 2.0 application?Thanks for any ideas.
