sabnzbd causes high system load

Hi all,

 

Is it normal that sabnzbd drives the sysload up to 143? (as reported in the top right corner of the web interface) 

 

I see three recently finished downloads (with "busy" spinners) in the History section, and one says "repairing 66%".

 

Can I tell it to behave better during this stage of the download process?

 

Thanks,

 

Tony

    I think the NAS runs fine until sabnzbd begins repairing one of the downloads. So, I'll switch that function off (per the last post here). And then hopefully I'll be able to see which downloads need intervention, and run those repairs manually from my Mac.

     

    However, now sabnzbd isn't able to start up. Are you able to take a look please?

    You probably should also post this in the sabnzbd forum.

        Does TOP give any clues?
