aria2 http/ftp download stuck at 0KB/s even with lowest-speed-limit set

[fawkes]

I use aria2 to download multiple files using ftp or http. This bug has appeared after version 1.15. I tested this issue with version 1.18, 1.23 and 1.24 . A while after starting aria2, it decides to stop downloading and gets stuck at 0 KB/s although i have set lowest-speed-limit=1K. Sometimes this issue happens within minutes of starting the download and sometimes it takes hours for it to happen. But when i set it to download files at night, every morning i find it stuck at 0 KB/s. This issue happens with and without setting max-overall-download-limit parameter.

Here are some more info that might help:

• parameters i use: -j2 -x8 -s4 -c -m0 --retry-wait=600 -i ~/shared/urls.txt -d ~/mb1/downloads/ --deferred-input=true --download-result=full --lowest-speed-limit=1K --log-level=error -laria.log
• urls.txt contains urls for multiple files to be downloaded.
• The computer executing aria2 has one IPv4 address and is behind NAT.
• I haven't tested this with torrents
• When connection speed drops below the value set for lowest-speed-limit, aria2 correctly stops downloading and continues with the next file but sometimes it doesn't happen and it gets stuck.
• Running aria2 with or without sudo permissions doesn't change the issue
• This happens both on Ubuntu Server 14.04 x64 and Raspbian Jessie (haven't tested another OS)

I make 2 commits to try to fix this issue.
It is still strange since timeout should be triggered where there is no network activity.

thank you so much for your fast response. I'll get the latest code, build and test it for couple of days and will report the results

I've tested it during the past 2 days and it doesn't seem to be happening anymore. Thanks for the fix.
