I can replicate the issue at my local LAN too. It is related to heavy traffic or packet lost/retransmissions. In this example, I started download in time when other process was using my server. When image was at 4.5%, server resources were free and zsync was downloading fast till it get 55% of the image; in that time other process put heavy load to the server and zsync has the problem again. Observed with zsync 0.5 at U9.04 amd64:
$ zsync http://server/zsync/ubuntu-9.04-dvd-i386.iso.zsync #################### 100.0% 1028.7 kBps DONE No relevent local data found - I will be downloading the whole file. If that's not what you want, CTRL-C out. You should specify the local file is the old version of the file to download with -i (you might have to decompress it with gzip -d first). Or perhaps you just have no data that helps download the file downloading from http://server/zsync/ubuntu-9.04-dvd-i386.iso: -------------------- 0.0% 12.5 kBps -------------------- 1.8% 10.9 kBps ETA -------------------- 1.8% 42.1 kBps -------------------- 1.8% 3.2 kBps ETA -------------------- 1.9% 68.1 kBps -------------------- 1.9% 24.6 kBps ETA -------------------- 1.9% 28.1 kBps -------------------- 1.9% 16.4 kBps -------------------- 2.5% 32.8 kBps ETA -------------------- 3.9% 49.2 kBps ETA -------------------- 4.5% 67.7 kBps TA ###########--------- 55.2% 3.6 kBps ETA ###########--------- 55.2% 10.9 kBps ###########--------- 55.9% 30.9 kBps TA ###########--------- 56.1% 3.0 kBps ETA -- Progress display prints spurious newlines https://bugs.launchpad.net/bugs/458063 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
