It's more likely that there's something wrong with the OS, firewall, virus scanner, router, ISP.
There are so many factors involved that it's a bit too easy to point
to SABnzbd as the guilty party.
Yes, it consumes a great deal of bandwidth, that's what it's for.
Do you have any other programs using as much sustained bandwidth
and what do they do?
Have you tried limiting the download speed?

The OS had recently (within three months) been reloaded on this machine. There are no other apps running on this or my main machine with any such sustained bandwidth. The only change to this system within the last week and a half was the addition of sabnzbd. Prior to this, I'd been using Newzbin Pro, which had consistently and constantly been downloading at 20+Mbps using 60 connections to Newshosting. I added the SABnzbd app and relevant folders to the Avira antivirus exceptions lists, as had been previously done with NewzBin. i'm not too concerned with the high bandwidth usage as much as the disconnection of this WinXP machine from the network, which then requires intervention. My main machine is not affected in any manner by this network disconnect.
Another thing I've noticed with sabnzbd is the sawtooth download performance, from 2.3+MBps down to zero, then ramping back up to 2+MBps, followed by a symmetrical drop to zero, then repeating. Sometimes my average downloads exceed 2+MBps, but most of the time they average between 1-1.5MBps.
I see great value in the automation features of sabnzbd and would like to continue using it. Are there any other specific areas that i can look at to try to eliminate this disconnect problem? Thanks for your assistance.

I don't recognize any way in which SABnzbd could block
network traffic, other that just using so much bandwidth that
other apps don't get a chance.
If you only get 2MB/sec on a system that could reach 20MB/sec,
it must be a very low spec system. SABnzbd is not very fast.
Are your numbers right. Is it bits/sec or bytes/sec.
A spikey download profile usually means that the system
cannot sustain the speed (SABnzbd's decoder/file-assembler
cannot keep up with the downloader and must hit the brake).
Do you have article memory cache setup in Config->General?
This could to wonders.
I can get 6-7 MBytes/sec on an WHS server running on a Atom CPU
and 11 MBytes/sec on a modest Core2Duo (100% of my ISP bandwidth).

The numbers are correct - Mbps = Megabits per second, MBps = MegaBytes per second. NewsBin Pro displays download speed in Mbps, whereas SABnzbd displays MBps. Didn't mean to confuse the issue by using both standards in the same context - merely trying to show the different performance numbers for both NewsBin Pro and SABnzbd - 2.0+ MegaBytes per second for NewsBin Pro vs 1.0-1.5 MegaBytes per second for SABnzbd. My ISP's max currently is 20Mbps, which is what I get using NewsBin Pro.
I originally had article memory cache setup, but eliminated it when my disconnect problems started. I can live with the spikey download caused by inadequate system processing, but the network disconnect is very problematic, taking the machine offline and requiring manual intervention. Killing the sabnzbd.exe process (or using the shutdown option in the browser) will then almost immediately allow the machine to reconnect to the LAN (monitored with a continuous ping in a cmd window.) Unfortunately, I'm unable to duplicate this problem on demand. Do you have any suggestions on reproducing the problem?
Thanks again!

I've never seen such issues.
The only thing I can suggest is to program a scheduled SABnzbd restart in Config->Scheduler.

Hi,
I have also experienced this running Sab 0.50 final on Ubuntu 9.10 using a 30mb wired connection on an AsROck Ion 330. It always happens when there is a few MB to go. The speed will read 0mbs and it will just hang there till I delete the NZB from the queue. Restarting SAB has no affect on this issue.
If you need any more info let me know.
Ian

This behaviors is typical (and unsolvable) in this scenario:
- Some articles are missing on all servers
- You have a primary (non backup) server
- You have a secondary server which is not online and is not "optional"
SABnzbd will forever keep asking for the article.
The first server will answer that the article is missing, but
the second server will not give an answer and SABnzbd will
keep asking it.
Servers that are known to be unreliable should be flagged as optional.
Note that this behavior can also occur when one of servers is very
slow in deciding that an article is missing. If you also set a relatively
short timeout, you end up in the same deadlock.

I'm having the same issues here tried everything, has anyone tried an older build?

It's a fundamental issue, which is in all the releases.
Actually the older ones are worse, because they don't know "optional" servers.
The alternative is to use limited retries.
But when your connection then dies, SABnzbd would quickly burn through all your queue
and say that it failed to download anything.
(Try it with Grabit).
We are looking at a way where you can manually tell SABnzbd it's enough and that
it should start post-processing.

I'm using sabnzbd 0.5.4 on a synology ds-410 dsm 3.0-1354 nas having a similar problem. every time i check last line of log it's something about my rss feed from nzbmatrix, not sure if it rss or tv/sorting function causing this? will clearing out cache folder for rss help this issue?
i've turned off rss and haven't had issue since but i'm not downloading as much so maybe i'll need a couple of weeks before i am certain. if it still locks up i'll set my server connections to 1.

Are you sure this is a similar problem?
Does SABnzbd lock up completely or is it that jobs don't finish?

Jobs don't finish, speed goes to 0 kb/s, i could still navigate in sabnzbd, i can still add more nzb's, delete nzb's but sabnzbd will not shutdown. i can shutdown sickbeard, couch potato only way to get transfers going again is to restart NAS then it resumes from where it left off.

RSS should have no influence on this.
So the same question: do you have multiple servers of which
one or more are not responsive?

only one server secure.usenetserver.com on port 443 with 4 ssl connections. u think i should try another usenet provider? it's strange every time this problem occurs when i check log file last line is something with sabnzbd retrieving rss from nzbmatrix it's like trying to parse nzb api key in rss folder.
