Reasons of "An existing connection was forcibly closed by the remote host" ? (2 replies)

Hello,
Once in a few days I see System.Net.Sockets.SocketException thrown, saying "An existing connection was forcibly closed by the remote host".

I don't understand the reasons for this exception. Our mysql server is not being shutdown at that time, clients and the server are in the same small local network.

So I want to ask the developers - what are the most probable reasons for this exception?

Here is a stack trace from the logs:


Exception type: System.IO.IOException
Exception message: Unable to write data to the transport connection: An existing connection was forcibly closed by the remote host.

Inner exception type: System.Net.Sockets.SocketException
Inner exception message: An existing connection was forcibly closed by the remote host

I tried to search all over the Internet to understand the reason but with no luck.
