I do reset the router every week or so, have good ethernet connection with fiber optics and 300 Mbps. No other issues. I've been with the same FTP server for several years (In Motion Hosting) and don't recall any issues, pretty good ratings. No problem ever uploading via other ftp clients. This was a large album, if that makes any difference. About 3800 files, but that's what I've always pretty much done. I appreciate your input, sounds like your really on top of this thing...

Thank you. Yes, I'm really eager to ensure that jAlbum's upload routine is as good as any other upload client. The problem for me is that it's hard to reproduce this problem. Are you able to give me ftp access to your account? (if so, write me at david_at_jalbum_dot_net). I'll then download and try uploading that very album to your server from here. If I'm lucky I can reproduce the error and work it out from there.
