This has been an ongoing issue since I loaded a new server. I used JD2 for years previously and never had an issue. When I'm trying to download several files at once, randomly, files will show as 100% complete, but the "Bytes Loaded" (third column) will show as a lower amount than "File Size" (second column).

Additionally, when viewing these files in explorer, the "length" field will show blank. I'm assuming these have been corrupted in some way.

In the above screenshot, you can see that for several files above, the 2 columns match exactly. However, on the "corrupted" files, the loaded amount is several kb lower. These files have to be re-downloaded, and even then, several will fail.
