ktorrent very high memory usage

[Chris Morgan]

Binary package hint: ktorrent

Left ktorrent running over night and it was using a crazy amount of memory.

Ubuntu intrepid amd64.

$ ktorrent --version
Qt: 4.4.3
KDE: 4.1.2 (KDE 4.1.2)
KTorrent: 3.1.2

$ apt-cache policy ktorrent
ktorrent:
  Installed: 3.1.2+dfsg.1-0ubuntu2
  Candidate: 3.1.2+dfsg.1-0ubuntu2
  Version table:
 *** 3.1.2+dfsg.1-0ubuntu2 0
        500 http://us.archive.ubuntu.com intrepid/main Packages
        100 /var/lib/dpkg/status

I see ktorrent using 1.2G of memory. There was another bug reported that looks like this issue but it was marked as fixed in 3.1.2+dfsg.1-0ubuntu2, but I'm still seeing the issue here.

The other day I had it using 60% of my memory.

[Bremm (bremm)]

Same here, and memory usage grows fast, at least 1MiB each minute. If I let ktorrent opened for 10 hours, it grows at least 600MiB in memory. This morning I saw it again with more than 700MiB, and starting to "eat" my swap.

I'm running the version below (3.1.2+dfsg.1-0ubuntu2.1) and the memory usage is growing faster.

OK, due to the possibility to run a Debian version of Ktorrent in Ubuntu, I gave myself a try. So far everything is fine.

I've found my answer here: http://ubuntuforums.org/showthread.php?t=1013086

"If you haven't had any luck upgrading to 3.1.5, you might want to take an extreme route and try using the Debian Sid repository (http://packages.debian.org/sid/i386/ktorrent/download). I wouldn't recommend leaving that repo active or using it to upgrade anything else, but it does have the latest version of Ktorrent."

So I did, and got it from here: http://packages.debian.org/sid/amd64/ktorrent/download

The other option "could be" download Ktorrent 3.1.5 and KDE4 upgrades from Jaunty, which could break whole system (and is unnecessary).

Things like that are bad propaganda against the distro, because Ktorrent *is* the default bittorrent client in Kubuntu.

The leaks should be fixed in KTorrent 3.2. Marking fix committed for now. I will close this bug once KTorrent 3.2 is released to Kubuntu 9.04.
