Description

Randomly when writing a large string (around 40 MB) we get this error:

Renci.SshNet.Common.SshException: Stale file handle
at Renci.SshNet.Sftp.SftpSession.RequestClose(Byte[] handle)
at Renci.SshNet.Sftp.SftpFileStream.Dispose(Boolean disposing)
at System.IO.Stream.Close()
at System.IO.StreamWriter.CloseStreamFromDispose(Boolean disposing)
at System.IO.StreamWriter.Dispose(Boolean disposing)
at System.IO.TextWriter.Dispose()
at Renci.SshNet.SftpClient.WriteAllText(String path, String contents)

Research direction

Start at SftpClient.WriteAllText and follow the stack trace through SftpFileStream.Dispose and SftpSession.RequestClose. Reproduce a write of a large string around 40 MB and investigate the reported stale file handle; done means the operation no longer raises this exception.
