All of a sudden... Multiple _UNPACK/_FAILED DOWNLOAD errors.. Advice??

Been using SAB for weeks with out a hitch. As of 24hes ago, multiple downloads are not completing. I went in the _FAILED_ETC... folders and tested them. It seems SAB is only downloading half the files then trying to unpack them. I use Newzbin service so I double checked the posts. I have only half the files that are reported on newzbin in the last 8 downloads.

I re started the Sab Service, and the PC multiple time. Seems to be getting worse. Out of the last 9 downloads, one was compled correctly.

What should I be lookign for? Has anyone seen this issue??

Thanks.

Examples. logfiles. Circumstances.
Do you expect us to say something useful without more info than you gave us?

I can think of many reasons besides SABnzbd.
Dodgy NZB files (yes, even on newzbin). Ill-tempered Usenet provider.
Do you have a reliable one?

Exactly same here. Sabnzbd 0.4.6 on OpenSuse 11.1, Default or plush interface, install from sources.

It happened few times since installing Sabnzbd 0.4.6. I just was able to reproduce it:

My queue file was corrupted, so I removed all files from cache directory. Ran sabnzbd and let it retrieve nzb files from my bookmarked list at newzbin. For a day or two everything was ok then all of a sudden - sabnzbd failed to unpack all downloads. Shutdown sabnzbd and rerun - now all downloads are pure trash and sabnzbd reports it'd downloading at the full speed but 0 connections to news server are active. Any shutdown/rerun wouldn't help.

This maybe related to the other problems
- shutdown from the browser gui doesn't seem to do anything. Regular 'kill' does the job only.
- any attempt to repair from par2 files is unsuccesfull (although there are plenty par2 files and I can fix the problem running par2 manually)

There is a potential problem in the filtering of illegal characters in filenames.
Any file name (not folder name) containing a semicolon ';' will be modified.
This will make par2 fail.

Release 0.4.7 (due soon) will correct this.

I'm not aware of any shutdown problem.

Do any of you two use giganews? I've heard increasing complaints since New Years.

I do use Giganews.
The problem of retension is noticable for old files (like e.g. older than 100-150 days) but exactly same files which fail - are easily downloaded with eg.Newsbinpro after couple hours. But - it maybe Giganews instability - right. Will take a closer look.


On the other hand -  par2 repair problem is neither specials characters like ";" nor giganews - I checked all _FAILED_* directories, 99% of them did contain  enough par2 valid par2 files which were easily repaired with 'par2 r' command (that what SABNZBD uses - according to the logs files).

I use multithreaded par2 - maybe this is the reason?

Same problem here. I think the issue is caused by the PAR2 filenames being slightly different even though they are in the same NZB file. Example below the extra PAR2 files where called "abigfile-other" whereas the downloaded RAR files where "abigfile"

Example log where it failed:

Stage Download
    [Time-Taken]: 4 hours 25 minutes 39 seconds
    [Avg-Speed]: 800kB/s

Stage Par2
    [PAR-INFO] abigfile-other: => Not enough repair blocks left (have: 0, need: 92)
    [PAR-INFO] abigfile: => Verified in 155.4s, all files correct
    [DEL-INFO] abigfile: => Deleted 2 file(s)

Stage Unrar
    [UNPACK]: => No post-processing because of failed verification

Turn "Ignore Sample Files" off. It is failed because the sample file was not downloaded.

In 0.5 I will have the option to delete sample files after the download to stop them failing like this.
