SABnzbd Forums

I've been running 0.5.3 on Windows 7 64-bit for a couple of months without issues but all of a sudden a strange problem started happening this past Sunday night. My downloads are now getting stuck at the unrar stage. The status in the history shows "Repair: Quick Checking" but it stays there for hours and the sabnzbd process shoots to 100%. There is also an unrar process still running and if I kill that it will then proceed to the moving stage and then fails with the message "Unpacking failed, [Error 299] Only part of a ReadProcessMemory or WriteProcessMemory request was completed".

I tried restarting sabnzbd first, then rebooting, but the problem still occurred with subsequent downloads. I then cleared the queue and upgraded to 0.5.4 which I'd been meaning to anyway but that didn't help either. I also tried starting it with the --clean option but still the same problem.

Has anyone else seen this?

Very occasionally we get a report like this.
It seems that on some systems the 64bit version of unrar doesn't work.
Disable 64bit tools, as described here:

(keyword allow_64bit_tools)

Let me know if this fixes the issue.

Yep, that seems to have done the trick. I had a hung download and a couple of other completed ones queued up behind it so I killed the sabnzbd process (shutdown failed) and changed the config file and they all completed fine after restarting. It's strange that it stopped working in the first place though. I checked my Windows Update history and there were a few security fixes applied on the day things stopped working so I suppose one of them might have been the culprit.

Anyway, thanks for the help. It seems to be working fine now which is the main thing.

Should it ever happen again, don't kill SABnzbd. That might corrupt your queue.
Instead stop unrar (or par2).
