error: Used to indicate that an operation cannot continue without blocking for I/O

[John Doe]

12/08/2011 11:40:47 - An I/O error occured, '....' paused.
12/08/2011 11:40:46 - Reason: .... file (C:/Users/[...]/Documents/Downloads/...) error: Used to indicate that an operation cannot continue without blocking for I/O

I shortened the file name, now it works..

I have the same error on Windows too. In fact I have received the error about dozen times already. Twice for about ten seconds qBittorrent was doing nothing but showing the notifications in the tray.

I can't confirm John Doe's conjecture above about file name length. In my case full file name is 73 (ASCII) characters long. That is far far below even the Windows' PATH_MAX.

I have the same error dozens of time.

The thing is that sometimes the qbittorrent let me to download the file.

And the file name thing,i don't thing it is because if i use another bittorrent client i haven't any problem to dowload the file

I've tried moving the file(s) to another location in order to shorten the path name - to no avail. I also tried to complete the download using another client (BitLord) but the same error occurred.

[Jonah Carik (jonah-carik)]

So I've tried µTorrent and that worked - the download was completed with no errors. I don't really like what µTorrent has become, but it will do for now.

this bug might have been fixed in 3.0.0 stable: the torrent that would always cause the same error now seems to be working fine. so far, at least.

I still get this in 3.0.0 stable (windows), and it's not because of path length. Works in uTorrent.

[Ben N (benjamin-nunns)]

Confirming this in 3.0.0. The error code translates to the Windows standard error message ERROR_CANT_WAIT with the long description being the one everybody is getting. The issue is not on a per file basis but on a per-piece (maybe hard drive sector?) basis by the looks of it.

File length has no effect - I've moved it to c:\temp and also tried a file paths around 200+ characters long.

*Really* the file does seem to work as long as it's changing drives or at least physical section on the disk - just shifting folders wont do this.

To properly move on the same drive, pause the download, zip up the file in question, delete the original, then unzip the file into the same spot again. Restarting the download should now allow it to complete (at least it has for 3 problem file's I've found).

Not sure what other torrent downloaders do differently, worth investigating though - the method above is a pain.

[jatjasjem (jatjasjem)]

taking my comment #6 back--the error still exists, although it is much less frequent than it was on older versions. thanks Ben, will try re-creating the files, hopefully will work at least for small torrents

I constantly run into this issue on bigger torrents (10 GB+). I can sometimes solve it by deleting the temporary data and letting it redownload everything but it's getting increasingly annoying.
