SABnzbd Forums

Hi

I'm running Sabnzbd 0.71 on a Synology 410j, and I'm getting some unusual pauses during downloading.

The Synology's "resource monitor" shows zero received data during these pauses, and also that the CPU usage drops considerably showing that the box is not just churning data.

The log file equally shows gaps corresponding to these pauses, with the pauses always between the following two events:
2012-07-16 13:25:48,328::DEBUG::[__init__:805] Saving data for SABnzbd_nzo_URSELY in /volume1/video/...
2012-07-16 13:28:57,605::INFO::[__init__:880] Saving data for totals9.sab in /var/packages/sab2/target/sab/admin/totals9.sab

Does anyone know what these events are, and have any solution to stop these pauses (they are typically several minutes in length, sometimes longer).

BTW, the "Pause Downloading During Post-Processing" switch is unchecked. I also recognize that the Synology box is a little "light" on resources (RAM in particular).

Thanks
Simon

It just means that the box cannot keep up with the download speed.
Make sure you haven't set too much article cache (it shouldn't cause swapping)
and that you've scaled down the # of cnonnections to the minimum required
for optimal speed.
The larger the NZBs are, the more time is needed for interim saves to disk.
That's why saves are done less frequently for larger NZBs.
Just how much memory does your box have?

Hi Shypike, thanks for replying.

The box only has 128MB, which from posts already on this forum I realise is too small.

Is this this pause the copying of the cache to disk? If so it seems a little long, given the cache at most is going to be a few MB. Could there be a reason that Sabnzbd is trying to copy the cache, but is being held up by the Synology's OS?

thanks
Simon

With so little memory you need to disable the article cache altogether.
Even then each article will be written to disk and when all articles for a file are in,
they are assembled into a file. This will take some time.
It's already positive that SABnzbd runs at all on such a small system.
