We have a Debian 8 file server with Samba 4, and there is a network printer-scanner, which send the scanned documents to the server through FTP in PDF format, and in the server the the Scan folder is shared through Samba, and mapped as drive on all client (mostly W7) machine.
And those scanned PDFs sometimes do not show up immediately in the share, just after a few minutes, but logging in to the server through SSH, I can see those files that the scanner sent, just the Samba not share them.
And its not just annoying, but if somebody scan a doc, which have to be send immediately in email, she/he is disrupted.
Anybody have any idea what's going on?
