Version: 0.12.17 (using KDE KDE 3.5.5) Installed from: Debian testing/unstable Packages OS: Linux Martin Bammer <bammer@plasmo-observer.com> reported the following on the Debian bug tracker (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=398895): k3b consumes 100 percent CPU and eats up all memory when starting an action like "Burn Image". - Burner is IDE - DMA is enabled I started k3b as follows: strace -f k3b --nofork After klicking e.g. "Burn Image" the output is: ioctl(6, FIONREAD, [1]) = 0 ioctl(6, FIONREAD, [1]) = 0 ioctl(6, FIONREAD, [1]) = 0 ioctl(6, FIONREAD, [1]) = 0 ioctl(6, FIONREAD, [1]) = 0 ioctl(6, FIONREAD, [1]) = 0 ioctl(6, FIONREAD, [1]) = 0 ioctl(6, FIONREAD, [1]) = 0 ioctl(6, FIONREAD, [1]) = 0 ioctl(6, FIONREAD, [1]) = 0 ioctl(6, FIONREAD, [1]) = 0 ioctl(6, FIONREAD, [1]) = 0 ioctl(6, FIONREAD, [1]) = 0 gettimeofday({1164790744, 27909}, NULL) = 0 ioctl(6, FIONREAD, [1]) = 0 ioctl(6, FIONREAD, [1]) = 0 brk(0x8505000) = 0x8505000 brk(0x8526000) = 0x8526000 brk(0x8547000) = 0x8547000 brk(0x8568000) = 0x8568000 brk(0x8589000) = 0x8589000 brk(0x85aa000) = 0x85aa000 brk(0x85cb000) = 0x85cb000 brk(0x85ec000) = 0x85ec000 brk(0x860d000) = 0x860d000 brk(0x862e000) = 0x862e000 brk(0x864f000) = 0x864f000 brk(0x8670000) = 0x8670000 brk(0x8691000) = 0x8691000 brk(0x86b2000) = 0x86b2000 brk(0x86d3000) = 0x86d3000 brk(0x86f4000) = 0x86f4000 The bug occurs independently what I want to burn. Always after clicking a Burn-Button the memory consumption increases endless. Gnomebaker works fine. In k3b the burn dialog doesn't appear. I think the problem is not related to wodim. I think the problem is in k3b. The brk-syscall is called endless (last lines in the log). I think a function, which reserves some memory and then fails is called in a loop. Maybe the return value and errno is not processed here.

hmm... K3bDeviceComboBox does not exist anymore. So this bug is obsolet.
Do you mean that K3bDeviceComboBox has been removed from K3b 1.0 ?

I have the same problem. Easily duplicated by erasing a cd. The computer becomes useless until K3B is done.
what if you erase a cdrw from the command line? you can get the command line from the k3b debugging output.
