skull icon for torrents on my uTorrent WebUI seedbox??

Can someone please let me know why some of the torrents I upload to my uTorrent WebUI seedbox keep winding up with a skull icon next to them as opposed to the normal happy face icon that they should have (see below)

Any thoughts on why this is happening, and how I can get it to stop happening? Is it a seedbox issue? An issue with the tracker? Something else? Any thoughts? Thanks!

As noted in the uTorrent documentation, the icon I am referring to ~ which typically appears with a black X on a red circle background, but appears as I described when using the "Aquazureus (alternate)" skin ~ means the torrent job has a critical error...

Why would something like this happen for some torrents and not for others??

I got it whenever my seedboxes HDD was full , AFAIK its a general error sign so there's no way to determine the exact cause

I think it means that the torrent is dead, usually due to hardrive space inefficiencies.

it means there is an error

I got this sometimes but then you can just start them again and it goes away. I don't know what causes this though.

Torrent error. Might be caused by HDD being under heavy usage, HDD being full, etc. I usually get these when I download several torrents at high speed (write errors).

delete torrent only ( not data ) then run it again it will check data then it will work

Mostly likely cause is not enough hard drive space. Delete some torrents and it should work fine again.

Had the same on mine the other day and it was due to full disk. Try upload data via FTP to confirm, should give you a quota error.

Thanks to everyone for some solid advice and guidance!

Also make sure in utorrents advanced settings that files are not deleted to trash bin. You can right click torrents and select remove+delete, but if this is active it won't really delete anything... just builds up in trash.

if ur using utorrent,disable the read/write caches this could help and wont hurt,to zset it back if need be!
