Could you please tell me what causes the error "Unable to find matching request for PASV connection from XX.XX.XX.XX" where the Xs are an IP address? We are experiencing this error repeatedly on high-traffic servers and can find no publicly available documentation on the error.
Any input or direction would be greatly appreciated.
jmorganthall, am I right saying you have quite old version of Serv-U? Probably version 6? I know this is not what you want to hear, but I really recommend you to upgrade as this one is end of life for a long time.
