It is as strange as it sounds. Everything was just peachy for a few days and then one day (after setting the app to shutdown the PC when finished the night before) I fired it up to find out the downloads were stalling after only a few minutes. The queue page never reflected this in the download speed or ETA indicators so I didn't notice for a while. The web interface still responds and I can navigate around but attempting to save any settings or view live data is no joy. Attempting to save anything results in a page timeout and all stats are stale data. After closer examination, I can see that this happens after 3.5 minutes from the time the app is forcibly closed and re-opened. I had the timeout for the servers set to 200 which is curiously just about 3.5 minutes.

As I type this, I realized whatever value I enter for server timeout in the servers config, that is how long it works until it barfs and stops responding. The web GUI seems to think the max is 200. Is there a way to make this unlimited?

I set the logging level to 3 and the last lines after the stall are not found anywhere else so I assume they are related to the problem:

2009-09-01 21:54:48,782::WARNING::[downloader] Thread [email protected]:119: timed out
2009-09-01 21:54:48,783::DEBUG::[trylist] Reseting .__try_list

I have 4 servers defined. Three are IPv6 over a tunnel broker and one is straight via v4. They all tank at the same time.

A longer timeout won't help. The timeout just specifies how long SABnzbd should wait for a server answer.
What you describe is what happens when a server is down
or very unresponsive.
Eweka's free ipv6 server is not exactly reliable.
Have you tried other servers or even another news program?

Like I mentioned in my post, I have 4 servers defined. One of them is the one I get free with my ISP and it always works. All 4 servers download at full speed for whatever duration I set the timeout to be and then abruptly stop. I have tried timeouts between 30 and 200 seconds and it is reproducible every time. I have newzbin and it works but I am not a huge fan of it. SAB is much better IMO.

Or perhaps I am not understanding how this app handles timed out servers. If one of the 4 times out, it doesn't affect the other 3 does it?

Try just the one server (your isp one), does download still stall?

If not, keep adding a server one at a time and wait to see if it stalls.

It is likely one of the 4 servers is blocking SABnzbd.

I think that's exactly what it was. This morning, all the servers are playing nice and not timing out so it isn't exhibiting that behavior. Is there a setting or tweak I need to apply to have it be more robust if one of my servers is being flaky so it doesn't hose up everything else and make me restart the app?

Thanks!

The next release (0.5.0) will have features to prevent unreliable servers from blocking everything.
0.4.11 has issues with this situation.

Thanks for taking the time to explain. I look forward to trying 0.5. Make sure you grab yourself a beer with the $20 spot I just donated. Cheers!
