80004005 Fatal error unable to write data to the transport connection

Hi,

I have a vb.net app which generally runs fine. But if it is up and running for a long time will get an error - which I have a screen shot of, but I see no way to attach a file to this message. So here goes (this is not verbatim) ...Fatal error encountered during command execution -> IOException: Unable to write data to the transport connection; An established connection was aborted by the software in your host machine -> Socket Exception: An established connection was aborted by the software in your host machine at yada yada yada.

The error message points to this source statement:

Dim sqlReader As MySqlDataReader = sqlCmd.ExecuteReader()

I strongly suspect that the problem relates to the fact that the connection usually gets used only once every 24 hours. I also suspect that the fix may involve TCPIP rather than MySQL. But I would have no idea where to look within TCPIP.

Can anyone here help me with this. I'd be grateful.

Thanks, Bob
