Seems to be random and not connected to any particular page. The SQL server is separated from the web server and my guess is that every once and a while the "link" goes down between the two.

I've not seen it triggered by any problems with the ASP code itself, which is why you're seeing it apparently at random and not connected to a particular page. share|improve this answer answered Sep 6 '08 at 3:49 Simon Forrest 2,2091420 add a comment| up vote 1 down vote I wanted to add this resource to the discussion here since this is such a common error and rather confusing to diagnose.

The error message is the generic [DBNETLIB][ConnectionWrite (send()).]General network error. Check your network documentation. This is reliably reproduced by leaving the app open for the night and resuming work in the morning. Since it's a backend server app this communication link failure is a normal scenario. The funny thing is - we've migrated from SQL Server 7 to 2000 to 2008 and the issue is present on all of them. But what seems to matter is the OS on which we run the app. On WinXP it works fine, on Vista/7 it fails. So the problem is at the client end. The results of Google on the error message cover a very wide spectrum of different causes (since this is a very generic error) and none of the scenarios found there are similar to ours. So perhaps someone around here will know what the problem is in our case? sql-server general-network-error share|improve this question asked Jul 9 '10 at 10:10 Vilx- 49.8k57194330 Does your app keep a single SQL connection open for the lifetime of the app? –Chris Bednarski Jul 9 '10 at 10:34 @Chris Bednarski - I think so, I'm not familiar with that part. –Vilx- Jul 9 '10 at 11:22 add a comment| 2 Answers 2 active oldest votes up vote 5 down vote You should be able to reproduce this error condition on demand by

Last night I set the program running on a continuous loop that reads values from a few tables, and updates a "heartbeat" record every few seconds - nothing else. This morning I found that after running for about 4 and a half hours it crashed with the following message:Number = 0x80004004Source = Microsoft OLE DB Provider for SQL Server Description =[DBNETLIB][ConnectionRead (recv()).]General network error. Check your network documentation.SQL State = 08S01NativeError = 11I am running it on a machine operating on Windows XP Professional SP2 and the version of SQL Server 2005 I am running is 2005.090.1399.00. The 3rd party application is running on the same machine as SQL Server. The only systems that interrogate the table are:1. The main program thread of the 3rd party application that does the work mentioned above.2. A MS Access front end that interrogates some of the tables (linked) once every 5 seconds using an On Timer Event3 There are 8 other threads running that are linked to the database on the 3rd party application but, when the application is idling as it was overnight, they do not interact with SQL tables at all.There are a total of 7 tables, the largest having 99 records.I have no idea what this message means or what to do to prevent it from happening. I chose SQL Server because I thought it was going to be robust but this is not inspiring confidence. Can anyone help me understand this message please?

Norton's antivirus seems to randomly conclude that the comms between client and server via TCP/IP is a Trojan Virus at work and stops it. I turned off the firewall and it appears to have fixed the problem. These comments are posted in case someone else has a similar problem.
