Version: (using KDE 4.1.2) OS: Linux Installed from: Ubuntu Packages This bug was reported at https://bugs.launchpad.net/bugs/285807 Version 3.1.2 using ubuntu 8.10 beta ktorrent on startup uses about 60% cpu, which seems very high compared to the usage of the kde3 version on hardy. But the real problem is, left for long enough, ktorrent consumes 100% of memory which effectively causes the system to crash. Leaving ktorrent open for a couple hours seems to be a reasonable period of usage, but I have to restart ktorrent after an hour or so, to stop my system crashing.
This is fixed in 3.1.4, which will be released this evening
