6.8.0 breaks FTP
After upgrading to OS6 6.8.0, scans from my Lexmark MX410de multi-function scanner fail if the .pdf file being written to is not altered within about 3 seconds. This is a new failure that did not exi...
We traced the cause of the issue, and have posted our findings to the ProFTPD bugzilla report. We should be able to get it fixed for the next 6.9.0 Beta.
Hello chainlinc,
I would like to verify the NAS and scanner is on the same local network? The 6.8.0 firmware did not made any changes on ftp access on the NAS. You have mentioned that if the resolution is set to low or medium it does work fine. There is a possibility that the NAS is lacking resources in scanning higher resolution files. Do you have ftp rate limit or ftp permission set on the shares that the scanner access. Can you provide the complete logs of the NAS, you may use file sharing website like wikisend and just PM the download link.

Both the NAS and the scanner are on the same local, wired network, both receiving a reserved IP address from the DHCP server.
Even low resolution scans fail when they are multiple page and the ADF is not used (the pause between placing the next page triggers the failure).
I set up a temporary FTP server on a Windows 10 Pro computer and the scanner scans to it just fine.
There is no FTP rate limit set. Permissions should not be an issue, as scans without a delay between pages work fine.
I will PM the logs.
Below are three entries from the proftpd.log file just created:
Entry 1 shows a successful scan to the FTP server.
Entries 2 and 3 are a failed scan and the error.
Does anyone know what the last character (c or i) in the first two entries represents?

Logs reveal that the OS on this ReadyNAS was updated to 6.8.0 on 2017-Aug-18.
Logs also reveal that the ProFTPD service on this ReadyNAS changed from 1.3.5b (maint) to 1.3.6 (stable) on 2017-08-18 (presumably by the firmware update).
It looks to me that the issue started from and is related to these linked updates.
Hello chainlinc,
It does appear that there is a bond set on the NIC cards what bonding/teaming is setup on the NAS? Have you try disconnecting the bond and just use a single ethernet port and then check the connection? Is the NAS connected to a Netgear switch?I have notice there are lot of logs listed below that I may need to check this with others who can probably assist us and get back to you as soon as possible.
Thanks for your cooperation!
