Question
-
I’m getting this error in a VMWare ESX environment. The application establishes a new connection for each transaction (yes, I know that’s not a good idea) but subsequent transactions generally succeed after I get a few of these failures.
I’m opening a support incident with VMWare, since it doesn’t seem to occur in a non-virtual environment, but I thought I’d post here too in case someone has seen something similar.
Thanks for your help,
Martin

We’re seeing the same thing as we’re supporting a company that runs an application that creates a new connection for each command.
Their hardware setup is a Dell 1800 w/Dual 3GHz Xeons and raid array, connected to a Cisco 2948 catalyst switch for network.
The database is running the 2005 version of msde… SQL Express i believe.
A host of errors they get… at least a few times a day
Error: 08S01 — Communication link failure
Error: 01000 — ConnectionWrite (send())
-
I have the same issue. Got any solution.
-
I have the same issue at around 1400 connections to SQL. Any resolution?
-
We have the same errors.. «Communication link failure» often preceeded by the «ConnectionWrite(send())» error. This is on a 3rd party application so we don’t know the internals of how it functions. Suspect that it likewise creates a new connection for each command but not really sure.
The application runs on multiple app servers and they connect to a dedicated database server.
Database server is 64 bit Server 2003 with 64 bit SQL 2005, 4 dual core processors, and 16 GB RAM.
We have looked at almost everything and cannot isolate the problem or find a solution.
Any suggestions would be appreciated.

I’ve got a customer with the same issue. They are the only customer I have running the queries over the WAN.
I had one example where trying to connect to one SQLServer server I got the message. Trying to connect to another server, did not get the problem. Rebooting the client machine solved (and typically solves) this problem.
If anyone has info on this, it would be greatly appreciated. Doesn’t look like this question’s getting much attention.

I got a similar message. I’m working on a VM and it says OLE DB error: OLE DB or ODBC error: Communication link failure; 08S01; Shared Memory Provider: No process is on the other end of the pipe.
; 08S01.When I try to process an Analysis Services cube.
Any ideas anyone?

Same here, please respond if there is any available solution.

I have an application that uses ADO to create recordsets on the fly and throw them away after reading data, using one connection object.
If used on a local
SQL Server 2005, the communication link failure occures when network connection broke down between two uses of recordsets. The temporary disrupted network connection (eg. WLAN) has nothing to do with the communication between application and server (local), and the connection is not broken at the time the error occures. This can be reproduced by temporary disconnecting any network connection.
The property Connection.Connected is still true after network connetcion failed temporary. So my workaround is to catch up the error at Recordset.Open, reconnect if Error.SQLState is 08S01 (setting
Connection.Connected to false and true), and try again.

Martin, i know this is a very very old thread but we are seeing this same issue. Did VMWare ever help on the issue (you had said you had a case open with them)? Brent

TruckinITGuy (Brent)… Did you ever determine a cause and get a fix for this? We are having the same problem on ESX. I found another article that suggested changing the value of SynAttackProtect (below). We probably have that set
to 1 for better security, I am going to try to set that back to 0 and see if that helps. But if you made headway, I would appreciate knowing how. Jeff
The following parameters can be used with this registry value:- 0 (default value): No SYN attack protection
- 1: Set SynAttackProtect to 1 for better protection against SYN attacks. This parameter causes TCP to adjust the retransmission of SYN-ACKS. When you set SynAttackProtect to 1,
connection responses time out more quickly if the system detects that a SYN attack is in progress. Windows uses the following values to determine whether an attack is in progress:- TcpMaxPortsExhausted
- TCPMaxHalfOpen
- TCPMaxHalfOpenRetried

I know this thread is old. Did anyone ever get this issue resolved? I am experiencing the same issue with VM running on ESXi 3.5 and the system had been running fine since 2008. Nothing has changed in the system, but users are getting disconnected
several times a day from our ERP system for two weeks now. SQL 2005 SP3 On Windows 2003 64 Bit.

We are also getting the out of memory error when processing an AS cube that had previously run fine.
«OLE DB error: OLE DB or ODBC error: Communication link failure; 08S01; Communication link failure; 08S01; Shared Memory Provider: No process is on the other end of the pipe.»
The Windows System Event Viewer Log revealed a ‘Resource-Exhuastion-Detector’ Warning:
«Windows successfully diagnosed a low virtual memory condition. The following programs consumed the most virtual memory: sqlservr.exe (1280) consumed 13694660608 bytes, msmdsrv.exe (5464) consumed 10279247872 bytes, and Ssms.exe (4032)
consumed 775794688 bytes.»We are expanded the PageFile on the VM and will see if that helps. We are also rebooting the server and performing delayed monthly maintenance, so that may also contribute to the solution.
The lack of memory has also caused the MSSQLSERVEROLAPService to crash and stop itself.
«The description for Event ID 22 from source MSSQLServerOLAPService cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the

The following information was included with the event:
Internal error: An unexpected exception occurred.
the message resource is present but the message is not found in the string/message table»

UPDATE: Expanding the PageFile on the VM seemed to have resolved the problem. The AS Cube processed successfully.

We used to have cases where our customer faced the following error messages like following:
- ERROR [08S01] [Microsoft][ODBC Driver 17 for SQL Server]TCP Provider: An existing connection was forcibly closed by the remote host.
- ERROR [08S01] [Microsoft][ODBC Driver 17 for SQL Server]Communication link failure
In this video below we going to provide us some insights about it.
Why this issue happens?
- Application or network issue at client level that closed unexpectedly the connection to the database
How to find the issue?
- Application Error messages: mainly followed by client driver names or protocols (ODBC/ TCP)
How to Fix the issue?
- Look for network issues.
- Check performance on target/application server
- Implement the retry-logic at connection and command execution.
In this video we will cover scenarios causing error — Communication link failure
Enjoy!
