Error: Connection reset by peer - recvfrom(2) about net-sftp HOT 4 OPEN

I think I resolved the issue. Previously I was using code similar to this to perform the upload:

Net::SFTP.start(...) do |sftp|
sftp.file.open(destination, 'w') do |handle|
  handle.puts builder.to_xml
end

Seems to be working when I do it this way:

Net::SFTP.start(...) do |ftp|
   ftp.upload(StringIO.new(generated_file.attachment.download), destination)
end

from net-sftp.

I'm getting the same error message, but uploading via FileZilla SFTP client works just fine. @dakingdom was the intrusion detection problem on the FTP server side or the local network you were uploading from?

The dropping of the transfer was either coming into our local network or within our local network. Always in the uploading direction. I tested it with scp and a large file. In this case a large file would be in the 200MB or larger range. Smaller files than that was not a problem. Sorry I guess, my reference frame for large file should have been clearer.

I am having this issue as well, but it's very sporadic. I have a bare basic implementation.

@con = Net::SFTP.start(@@host, @@username, :password => @@password)
@con.upload!(filepath, destination)

I had this running like this for several years when suddenly this year it started throwing this error. But not all the time, only sometimes. Sometimes it works with no issue. I've talked to my sftp host and they tell me there is no problem on their end. I'm transferring xml files and images in the < 5MB range. Any troubleshooting advice is appreciated.
