Your DB when FTP refusing my FTP

Hello admins as I expected another problem regarding FTP, I observe every a couple of minutes refusing to upload my files using FTP. pls. help. TY

Try edit, then settings, then make sure the max is 1 to see if this helps.

im using a weather station which uploads single files every 15 seconds and the software sends weather files one at the time, because it uses realtime reporting, it refuses when a single file to be ftp is refused and when the refuse time is much extended, causing of continued refusing, the result that the DB server thought it sends multiple files at once even though its not. Heres my weather station ftp log, as you see that it just sending ONE file evry 15 seconds and other image files per interval time, and doesnt need to upload multiple files at once because it will ruined its data reporting, so I already limiting its concurrent ftp. I think the DB is always requesting IP address even my server already sending IP address, this is mostly the cause of a frequent refusing ftp, maybe try to look on the nodes. Thanks.
