MySQL: Received an unexpected EOF or 0 bytes from the transport stream

I get the error below from an application I am running. I only have access to log, but not to the code.

Several SQL queries are returning results as expected then all of a sudden I see this error. Any idea what may be happening? I would have expected no queries to have completed if there was an issue with SSL. But it only happens after a few queries have finished execution and returned results.

The calling function is MySql.Data.MySqlClient.MySqlDataReader.Read()

   MySql.Data.MySqlClient.MySqlException (0x80004005): Reading from the stream has failed. 
    System.IO.IOException: Received an unexpected EOF or 0 bytes from the transport stream.
