SQL Server 2000 Error 17805 Invalid Buffer Received From Client
Oct 23, 2005
Hi,
I've developed an ASP.NET application which uses MS-SQL Server 2000 as a
backend. But as the site hits increase SQL server reponse becomes lower.
At some stage after that SQL Server gets automativally stopped bringing
complete web-application down to halt. i checked the Windows 2000 Event
Logs and found several error logs indicating folloowing line.
"SQL Server 2000 Error 17805 Invalid buffer received from client.". But
no errors on UI side. What may be the actual problem.In storedprocedures
or at some other place?
Awaiting favourble reply.
Regards,
Amit

Howdy Folks, Our site has been experiencing this issue for a couple of months now.. Hopefully someone else can assist, as I’ve got to a point where I think issue lies within the application or a Microsoft bug. Web searches have reveled a number installations that have also had this error but its has not revealed an actual fix.
I understand this error code basically means data being returned to the client is getting either corrupted or the data is too large to fit into the buffer on the client side. Client in our case is the terminal server, here after called a application server
As the user base has increased form 5 to 20, I have noticed that the issue is occurring more frequently in comparison to when the company first started using the application /database. Its just about daily now...
The db server also has 8 other db's residing on it - but they are all less than 300 meg.
The attached PowerPoint doc has the trace info & the surrounding code for each process that has suffered a buffer error over a period of a week.
DB Server Environment: Win2000 SP4, SQL2000 SP3a, MDAC 2.7 SP1 refresh. Application Environment: Written In house in VB.NET Framework 1.1 – setup as a published app on a terminal server – running windows 2000 SP4
Common features of the issue, that have been omitted from trace output for visibility reasons are: -Involves 1 particular DB (thats accessed by VB app) & its developement db -All connections are coming from 1 application server -Issue does not relate to any particular site connecting to the application server using this application
I have reviewed & fixed several potential server side causes but this error still is occuring with in the environment:
MDAC versions must be common on application & server: - Removed from equation by updating MDAC version on App server to be the same as DB Server: 2.7 SP1 Refresh
Network related - Considered unlikely; we are also not experiencing network card errors on either server; also all db's would be experiencing connectivity errors.
Which leaves us with Application related options to review: - Compilation error of application - App parameter definitions to stored procedures are the correct data type - Ensure values being passed do not exceed 4000 characters as that has also been known to create this error message - I've asked the developer to review MS KB 827366 article, as it may be a valid test - In regard to MSKB 832977 - I am not using pssdiag & have a later version of the MS Analyzer. But what I thought was interesting, is the statement that this problem occurs more frequently when an application submits a large remote procedure call (RPC) input buffer, especially when the RPC input buffer is greater than or equal to 8 KB. However, this problem may occur even if the input buffer is less than 4 KB - A is using datatypes varchar & char - not nvarchar & nhar
Any assistance with this issue would be appreicated as server performance is being effected - these processes hang around for 1 - 5 mins before terminating (refer duration times in the powerpoint traces)
when i tried to run a DTS which transfer bulk data between 2 SQL servers, i got following error message: ================================================== ============ Error: -2147467259 (80004005); Provider Error: 4815 (12CF) Error string: Received invalid column length from bcp client. Error source: Microsoft OLE DB Provider for SQL Server Help file: Help context: 0 ================================================== ===========
if anybody has encounter the same problem before? after testing, i think it's must related with network traffic problem. but i can not figure out how to solve it.
My sql server 7.0 sp2 hangs occasionaly. When looking at the sql connections they are all working and then al of a sudden they go to 0 and the clinets that are searching arewaiting for about 30 seconds or get timed out.
Also the CPU could be at 25% and then goes to 0 then back to 25%
I am also getting the error 17805 Invalid buffer recieved from the client.
this is to do with the ODS.( microsoft info)
Any suggestions as to what is causing this.? or has anyone else encountered this before.
I encountered the following error while attempting to preview an RDL report I was developing in VS2010 using SSDT:"The size necessary to buffer the XML content exceeded the buffer quota"
I have a master package that executes a series of sub packages run from a SQL Agent job. One of those sub packages has been stable for a week, running at least once per day, but it just failed despite having been run once already today with the same set of input data.
There were a series of errors showing in the event log for the Execute Package Task starting with "Buffer Type 15 had a size of 0 bytes.", then "The buffer manager failed to create a new buffer type.", then "The Data Flow task cannot register a buffer type. The type had 32 columns and was for execution tree 3.", then "The layout failed validation." and finally "Error 0xC0012050 while loading package file "C:[Package].dtsx". Package failed validation from the ExecutePackage task. The package cannot run.".
SQLIS.com reports the constant for the error code as DTS_E_REMOTEPACKAGEVALIDATION ( http://wiki.sqlis.com/default.aspx/SQLISWiki/0xC0012050.html ).
I then ran the package on my dev machine in BIDS and it worked fine, so I re-ran the job on the server and this time that package executed ok, but another one fell over but did not put anything in the event log.
Please help. I have Error 17805 Severity 20 State 3 in my SQL Server Log. I run SQL SERVER 2K with servie pack 3 on Win 2K AdvncedServer pus service pack 3. Clients access the server over the internet.(SQL Server is database engine to e-commerce site) Please help as the error was logged twice within an hour apart.
I've SQL Server Reporting Services 2005 configured on my system, but now I'm NOT Able to start the report server. I get this error on http://<serverurl>/Reports/Home.aspx:

Check the documentation for more information. (rsReportServerDisabled) Key not valid for use in specified state. (Exception from HRESULT: 0x8009000B)
I don't want to loose any data. Please help me resolving this error.
FYI, I've modified the SQL Reporting Services account LogOnAs info, in Properties of "SQL Server Reporting Services (MSSQLSERVER)" Service, in Windows Service Managment.
Earlier I had .useraccount as username, I modified it to domainnameuseraccount. And then suddenlt everything broke for reporting server.
Upgraded Enterprise Mgr. from SQL7 to SQL 20000. When trying to connect to SQl 2000 server using Enterprise mgr using TCP/IP am getting Invalid attribute/option identifier any suggestions???
I've check out that this error code says: A literal value in the command overflowed the range of the type of the associated column.
I received the error message when inserting large block data into a image column in SQL Server 2000. As I know, image support max 2G data to store. I use the C code function below to insert the data:
in which, the NUM_SAMPLES_SETDBMONITOR*sizeof(float64) stands for the data length by byte. and ,&(pMonitorDBData->SampDat) stands for the pointer address of the data block. (pls note: NUM_SAMPLES_SETDBMONITOR*sizeof(float64) = 4096*8=32768 bytes)
In addation, I've tried to use certain numbers instead of "NUM_SAMPLES_SETDBMONITOR*sizeof(float64)", and I found I could only set this value up to 8003 bytes. If 8003 above, this error message would be received.
What should I do with this issue? Any help? Thanks a million!
I have a SQL 7 Enterprise Edition production server. I have installed SQL 2000 personal edition on a client station. I wish to use the 2000 tools to view,modify and create objects on the SQL 7 production server. These include stored procs,tables,dts packages etc.
What are the potential pitfalls of this. I am using this strategy to introduce myself to the SQL 2000 enviroment, and perhaps utilise some of its benefits.
I have a vb 6 program that has been running for several years against a 6.5 db. I convert the db to 2000, and now when I repoint the software to the 2000 db, I get "Invalid Authorization Specification" when I try to open the connection. The connection string is:Dim conn As ADODB.ConnectionSet conn = New ADODB.Connectionconn.Open "Provider=SQLOLEDB" & _ ";Data Source=" & sServer & _ ";Initial Catalog=" & sDB & _ ";User Id=" & goProcess.UserID & _ ";Password=" & goProcess.Password & ";"All of the variables are filled out correctly, when I go against a 6.5 it works, Sql Server 2000 doesn't.
Hi,I used SQL Server 2000 Personal Edition. I created a stored procedurehaving input parameters as smallint,tinyint,char,varchar andsmalldatetime. When I executed it by Query Analyzer, it's ok. But whenI executed it by ASP code that used ADODB.command, it showed error:Invalid character value for cast specification .Though SQL Server debugger, it showed:[Microsoft][ODBC SQL Server Driver]Invalid character value for castspecificationWhat did I do wrong? How do I fix this problem?TIAKrungPS: One of input parameters was smalldatetime, but I casting it in ASPas date as:Const adDate=7datetxt='2004/6/28'cmd.Parameters.Append cmd.CreateParameter("CoopId",adChar,adParamInput, 8, coopid)cmd.Parameters.Append cmd.CreateParameter("Addr",adVarChar,adParamInput, 100, addr)...cmd.Parameters.Append cmd.CreateParameter("Cdate",adDate,adParamInput, , datetxt)....cmd.execute
I'm working on a database conversion from Sybase to SQL Server 2005 and have hit a wall with a character conversion problem when reading non-ASCII characters (encrypted password) via JDBC.
My application runs on Solaris and accesses a SQL Server 2005 database via the Microsoft JDBC driver. The server was unfortunately specified as having a SQL_Latin1_General_CP1_CI_AS collation at installation time, and the database being accessed has taken this default. After creation the data was migrated across via DTS.
The invalid character is a dagger '€ '. When read over JDBC it is converted to a question mark '?'.
In my original environment a Sybase database was accessed via JDBC driver from Solaris and the correct value was returned. The Sybase database used Latin1_General_BIN as it's collation. By way of experimentation I have modified the default collation sequence within the SQL Server 2005 database, and created a new table to hold the password. I am then able to correctly return strings containing this character from within SQL Server Management Studio, but the same problem still exists when accessing it via JDBC.
I am not sure where to focus my investigation and would be grateful for any useful pointers/advice. To me it looks like it's a JDBC driver issue as with the change in collation it works from a non-JDBC client.
According to MS Knowledge Base Article 269824, "[SQL Server 2000 ClientTools] ... must be installed ... on any computer on which someone may makedesign changes in an Access project to a SQL Server 2000 database".This is the situation I'm facing. Can I download these Client Tools andinstall them for free, or are they only available on the SQL Server 2000Installation CD?Thanks for any help!
I have SQL Server2005 client in my system,I am able to connect SQL Server 2000,but I am unable to create DTS packages.2005 client not at all showing Local packages icon to create package.
any body experianced with this Please guide me ragarding.
When you connect to SQL Server using SQLConnection, how to set client machine name(or IP address) so that you can monitor the process on Server side using Enterprise Manager?
I'm trying to remember how to install the SQL 2000 client tools onto a SQL 2005 server. There are a couple of bizarre steps that will allow this to happen, but I can't for the life of me remember what comes after the unicycle down the stairs with the umbrella stand of machetes.
Can anybody remember the magic, or do I resort to using VPC to kludge the install until I can find my clay tablets again?
I'm having difficulties when connecting to our SQL server 2000 from my SQL Server Mgmt Studio 2005. I can't create tables and columns due to permission errors. But from 2000 (on a different machine) it works fine. *Sometimes* even when I log in with my AD account it won't let me in and complains that user 'null' is not authorized to log in...
Anyway, I've installed both SP1 and SP2 and the problem still persists.
Any help is appreciated.
P.S> I tinstalled SQL 2000 on my machine but that didn't help either; I guess the 2005's configurations are being read by 2000.
I have recently installed SQL 2005 client tools with SQL Server Management Studio and accessing databases on a SQL 2000 server. The response I am getting is extremely slow. Should I go back to SQL 2000 client or are there methods by which I can improve the performance.
Hi, I have a server (WIN 2000 server), is connected with many clients mostly having Win 2000 Professional OS. My application is developed in VB 6.0 and we have MS SQL Server 2000 DB in our server. All the clients with win 2000 professional have no problem with connecting and accessing my SQL Database. But few of my WIN XP clients don€™t connect to database thru my application. It gives error as follows.
Runtime error Login Failed for user €˜(null)€™ . Reason: Not associated with a trusted SQL Connection.
I have a 500-MB full installation CD for SQL Server 2000. All I needis to install "Client Connectivity" component (about 272K) on a bunchof workstations for users across the nation.How do I reduce the installation file size, by eliminating most of theunwanted files?Thanks.
I am trying to create several Excel sheets using SQL 2000 views like so:
Select * INTO [Excel 8.0;Database="C:spreadSheetsaNew.xls"] FROM [aView].
When I try and execute this in my app I get the following - Specified owner name 'Excel 8.0;Database=c:spreadSheetsaNew.xls' either does not exist or you do not have permission to use it.
If I use the above Select statement with an OLEDB connection it works.
I am using Imports System.Data.SqlClient, instantiating a new SQlConnection object, opening the connection, etc..

We have a set of reports with same header section in all the reports. So while developing a new report i used to copy that header section to the new report with same dataset names (without any change) , but while rendering the report it is throwing error " The size necessary to buffer the XML content exceeded the buffer quota".
