The Client Was Unable To Reuse A Session With SPID XX
May 11, 2007
Hello,
We have a recurring problem with one of our MS SQL Servers (MS SQL Server 2005 SP 1).
The SQL Server serves as a database server for a Web application with approximately 1500 users, the server is dedicated for the DataBase server.
The scenario is that the database servers cpu peaks at 100% and stays there until restart of the SQL Server service.
The error message from the applicatoion log:
Event Type: Error
Event Source: MSSQLSERVER
Event Category: (2)
Event ID: 18056
The client was unable to reuse a session with SPID 94, which had been reset for conection pooling. This error may have been caused by an earlier operation failing. Check the error logs for failed operations immediately before this error message.
SPID varies.
Anybody that knows anything why this error occurs?
Regards
John

Hello,
We are running SQL2K5 and have a Web server with a family of sites all sharing an identical connection string to enable ADO connection pooling between them. Today for about 20 minutes we had several (all?) connections from one site that uses a specific DB get a connection reuse error which showed in out SQL logs:
DESCRIPTION: The client was unable to reuse a session with SPID #, which had been reset for conection pooling. This error may have been caused by an earlier operation failing. Check the error logs for failed operations immediately before this error message.
We also have SQL Server slowdown and log in problems from other applications that seemed a symptom of this, or some third unknown cause. Note, the # means the run-time spid number was inserted. The misspelling "conection" comes right out of sys.messages (it is not our custom error):
select top 10 * from sys.messages where message_id = 18056
The immediately preceeding error in the SQL Log was always:
Message
Error: 18056, Severity: 20, State: 29.
Where Severity and State vary, but "Error: 18056" is consistent, although I can find no documentation on "Error: 18056" through Google or MSDN.
Also, the "The client was unable to reuse a session ..." error seems not to be referred to anywhere.
In our IIS logs, the matching entries are of the form:
[DBNETLIB][ConnectionRead (recv()).]General network error. Check your network documentation.
and
Invalid connection string attribute
My questions: Does anyone have experience with this error? We have real good history with ADO connection pooling, but can a "bad" connection be pooled, and if so can it be "flushed" or the pool "drained"?
Thank you for anything you have to offer!

On Windows XP systems I get the following issue when trying to browse the MSDB folder in SSIS
Client unable to establish connection
Encryption not supported on SQL Server. (Microsoft SQL Native Client)
I have noticed another post where several others have noticed the same issue. It appears to only occur on Windows XP installations. Is there a workaround or fix for this?

Here are the error messages:
Enterprise Manager:
A connection could not be established to SERVERNAME - Client unable
to establish connection ConnectionOpen (CreateFile())
Query Analyzer:
Unable to connect to server ServerName

I can't register any other new servers, even ones in my workgroup. I'm connecting using named pipes, but have also tried using TCP/IP setting it up using Client Network Utility.
When i log on to another machine using my network login - I can connect.
There have been no problems connecting in the past and I haven't changed anything on my machine - any ideas???

Hi Guys.
We have a clustered server. When i create DTS packages in the secondary server I can get all the connection. But when i create DTS package that has connection to other servers. I am getting the follwing error. So my jobs that runs the DTS packages are failing.
Error Source: Microsoft OLE DB Provider for sql server
Error Description: Client Unable to establish connection.
Connectionopen(createfile())
I deleted all the entries in the Client network utility and recreated with ip addresses and TCP/IP protocol.
Added all the ip addresses to Lmhosts and host files.
Check the Server Network Utility.
I dont have a clue now.
Anyhelp are well appreciated.

Hi,
I have a Visual C# WinForms app which I am accessing a SQL Server 2005 database with. On the Server, I have allowed remote connections (TCP and named pipes) and enable SQL Browser as per instructions on MSDN. The app works fine on the development machine.
Server name is <machine name>SQLEXPRESS, connecting with Windows Authentication.
Server log states that it is listening on [ 'any' <ipv4> 3153].
Server named pipe provider is ready to accept connection on [ \.pipeMSSQL$SQLEXPRESSsqlquery ].
On the client (local network), when trying to open the database I get this error still:
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
Also on the client, I can go into the ODBC Data Source Administation, and connect to the SQL Server Database that way successfully.
What further steps can I take to allow the client to access the SQL Server?

Hi,
I have SQL Server 2005 installed and functioning (it does everything I've asked it to do locally). I also have the Express and Standard Editions installed on a computer running WinXPPro SP2 with all the WinUpdates applied. I also have VS2005 installed on this computer. I've done some development work on this computer, using VS2005 to create a SQLDB, connect to it, add data, etc. This is all okay.
The problem is I cannot connect to the SQL Server from the client computer. I installed the client tools on this XP Pro box along with all the WinUpdates. Here's what I can do...
I can ping the SQL Server by name (the name gets resolved).
I can copy files between the two computers using Explorer.
I enabled "Allow remote connections to this server" in the Server Properties / Connections page.
I did not change the default port of 1433.
The TCP/IP protocal is enabled in the Configuration Manager.
The Surface Area has been configured to allow local and remote connections using TCP/IP and named pipes.
SQLBrowser surface is running as is the MSSQLSERVER service.
So what's going on? I am new to SQL Server to it may be something very simple / obvious.
Thanks for your help,
Scott

HELP!
I'm new to SQL Server and I'm sure this is a simple problem.
But I can't seem to solve it.
Here's the problem:
My website & MS SQL 2000 Server are being hosted by Networksolutions.
Thru the Client Enterprise Manager I am Unable to create a New Table.
This is the error message I get:

Hello,
I was hoping someone had this problem and has a solution... :)
Some background info:
SQL 2005 Enterprise x64
Windows 2003 R2 x64 Enterprise (clustered)
Oracle client 10.2.0.3 (latest as of 2/2/07)
The issue I'm having is I have a link server setup within SQL 2005 connecting to a Oracle 8 database server. The Oracle client I'm using is 10.2.0.3 (latest version from Oracle). From the SQL 2005 server I'm able to query the remote oracle server through the link server I had setup if I query the table directly. If I perform a query to a view on the Oracle server I'm able to see the colum names, but not the data. This only happens when I'm using the Oracle client, if I use the MS client for Oracle it works fine OR if I use SQL Plus.
Now, you're probally asking, why not just use MS's driver... Well, I would If I could, but Microsoft hasn't provided a 64 bit driver for Oracle which I need to create the link server in SQL.
Any help would be appreciated.

Hi, I have a Active/Active SQL 2005 Cluster, and I've seen this recurring message in the Event Log.
Source: SQLBrowser
Category: None
Type: Error
User: N/A
EventID: 8
Message: The SQLBrowser service was unable to process a client request.
I don't know if it's something to worry about, since I haven't had anyone call in an issue.
I have set the default and named instances to specific ports, no dynamic ports here.
There's nothing in the instances' error logs.

Hi to everyone!
Here is my problem: I have SQLEXPRESS running with Windows Authentication on a "server" PC named "ASUS1", and I need to connect from a "client" PC named "Presario1", user "Mauro", connected through a peer network (I use a cross-over cable); both PCs belongs to the same workgroup named "RMT-WORK", and they can see each others shared folders without problems.
I have installed the connectivity components + Management Studio Express on Presario1, and enabled named pipes and TCP/IP protocols; then I've got SQL Browser running. I have also added the Login "Guest" on ASUS1SQLEXPRESS.
When I start Management Studio Express on Presario1 and browse for servers I can select "ASUS1" as database engine but when I try to connect I receive "Error 40: could not open a connection to SQL Server" (same result using SQLCMD); I have tried to add on ASUS1SQLEXPRESS a user "Presario1Mauro" with "CREATE LOGIN [Presario1Mauro] FROM WINDOWS" but I receive a "Windows user not found" error...
Can anyone help me?

We have recently upgraded our .Net web application from a windows 2003 server to a windows 2012 server. Since this happened users that are trying to print a reporting services report is getting the error "Unable to load client print control". We are using reporting services 2012, but the application is using the 8 version of the viewer. The reporting services server did not change only the application server. The code for the application did not change.

Hi,
I currently have SQL2005 Std, using 2 separate domain accounts for both SQL server and SQL agent. When accessing the MSDB stored packages folder from mgmt studio, I get the following error:
Client unable to establish connection.
Encryption not supported on SQL server.
I did google for this error, but have tried all suggestions, including updating the MsDtsSvr.ini.xml file with the servername. I am using a default instance.
Also, I am only able to access the MSDB folder if I set the SQL service account to the local admin account. I have also set the SQL service account to be part of the local admins group, but without any luck.
TIA.

Hi all,
I have downloaded Microsoft SQL Server 2005 Enterprise Evaluation Edition ISO from the following site and burned it onto a DVD.
http://www.microsoft.com/downloads/details.aspx?FamilyId=6931FA7F-C094-49A2-A050-2D07993566EC&displaylang=en
Prior to this I have installed Visual Studio 2005 Professional Edtion. During setup I have selected all the native client components i.e. Management Studio, Business Intelligense Studio. But after the install I am not able to see them under All Programs-> Microsoft SQL Server 2005. On further searching I have come across this link
http://channel9.msdn.com/ShowPost.aspx?PostID=142941
First of all, there is no sqlrun_tools.msi under setup folder of the dvd. And also when I tried to change component from Add/Remove programs and following the instructions as specified on clicking Change Installed components all that I see are: Connectivity Components and Software Development kit.
Could someone tell me how can I install Management Studio/ Business Intelligence Studio seperately? I don't want to go through the process of re-installation.

The 2.0 version of ASPSTATE is slightly different than the 1.1 version in that one table has one additional column and another table uses a different data type and size for the key. The 2.0 version also has a couple additional stored procedures.
We'd like to manage just one session state database if possible so we're trying to figure out if Microsoft supports using the new schema for 1.1 session state access (it seems to work, but our testing has been very light).
Is there any official support line on this? If not, can anyone comment on whether or not you'd expect it to work and why?
Thanks.

Hi,
I am getting the following error:
The SqlParameter with ParameterName '@pk' is already contained by another SqlParameterCollection
If I could work out what code to post I would, but I can say that I am managing my Sql data in my code by caching small arrays of SqlParameter objects as pulled from the database. If I need to update the DB I change the cached SqlParameter and re-insert it. If I perform a SELECT I check the cache first to see if I already have the SqlParameter.
However, currently, I am experiencing the above error when performing a select, then later an update, followed by another update.
Would I be correct in saying that a SqlParameter object can only be used once for a database operation and should be discarded? Would I be correct if I said that the SqlCommand object should be discarded? I am barking up the wrong tree entirely?
Distressed in DBLand,
Matt.

I can create a SqlCacheDependency, and link it to a cached item in httpcontext cache. When something change, it will remove the cached item from the cache. I think I have to redo the process when that happens - prepare sql command, create SqlCacheDependency and insert the item into cache. Now I only need a notification from my SQL when something changes in one of my table, I don;t need read anything from db, and I think I should find a way to not recreate the SqlCacheDependency object everytime?
any suggestion?
