Hi, I've have an application that is running on multiple sites but on one site recently I've got this error twice over a few weeks. Restarting the applications seems to fix the issue. This is my connection parameters <DATABASE> <SERVER>192.168.1.252</SERVER> <USERID>username</USERID> <PASSWORD>password</PASSWORD> <NAME>database_name</NAME> <POOLING>FALSE</POOLING> <LIFETIME>60</LIFETIME> </DATABASE> Here is my VB.NET code SQLString = "SELECT GPSLogID, PrimaryAssetID, Longitude, Latitude FROM tblGPSLog WHERE Location = '' ORDER BY GPSLogID ASC LIMIT 100" ' SQL Command parameters myCMD.CommandType = CommandType.Text myCMD.CommandText = SQLString myCMD.Connection = myConn ' Execute the SQL Statement myCMD.CommandTimeout = 5000 MySQLReader = myCMD.ExecuteReader << THIS IS LINE 133 The full error is Source: LOCATION Event: GPSLOG Date Stamp: 2012-05-10 00:32:59 Error: LINE 0 : UNABLE TO WRITE DATA TO THE TRANSPORT CONNECTION: AN ESTABLISHED CONNECTION WAS ABORTED BY THE SOFTWARE IN YOUR HOST MACHINE.

I've checked the hostname.err file and there is nothing in there. I've checked the windows logs around the time of the error and again nothing to indicate a problem. There's no pattern to this at all. As the application works 99% of the time for this customer and 100% for all the other customers I really don't have a clue where to start looking. Thanks

Error: LINE 0 : UNABLE TO WRITE DATA TO THE TRANSPORT CONNECTION: AN ESTABLISHED CONNECTION WAS ABORTED BY THE SOFTWARE IN YOUR HOST MACHINE. It could be problem with network connection. For VB queries, post here. http://social.msdn.microsoft.com/Forums/en-US/vblanguage/threads Thanks
