Error 87, sabnzbd assembles faulty archives

[KuroNeko]

Using 0.7.1 on Win7 HP 64, Windows installer, default skin, mostly default settings, Win7 firewall, issue is reproducible.

I've been using sabnzbd for a few years now, without many issues. For the past few weeks, Giganews is having trouble with some posts, with many incomplete articles or corrupt articles. That shouldn't be a problem, usually I can get some parts on an alternate server and manually fix it.

But sabnzbd is now assembling faulty archives instead of leaving them alone. I for instance just downloaded a 16 GB file, 174 parts. sabnzbd reports an error 87 incorrect parameter and says repair failed. Next it starts joining files anyway and deletes the parts. 16 GB down the drain (which is a lot here, no real broadband access).

What is wrong, and how can I stop sabnzbd doing this? I could disable the postprocessing entirely but I'd rather it just leaves downloads that don't repair alone. Too much manual work otherwise.

It no use asking for support for 0.7.1, when we're already on 0.7.6
Please try 0.7.6 first.

So this is a know issue fixed in 0.7.6?

What's holding you?
Nothing is going to be fixed in 0.7.1 any more.

I'll update once the queue has finished. But from your response, I take it it's not a know issue, so I guess I'll be back soon.

Can you show the exact error message in the download report (click on the History entry)?
One work-around may be to disable the "Enable MultiCore Par2" option ibn Config->Switches.
The multi-core par2 program has some issues that the standard (slower) par2 doesn't have.
