Ok, I took a closer look at it. It's about the resolution of the .02 value: | while values and (t + values[-1 - c] < (tm * .02) or | ^^^ If I change the .02 to something lower like .005 it works. Variable tm (:= total memory) corresponds to 511964 kbytes on my system. So 2% of it are ~10239 kbytes. I don't have any processes which consume more than those ~10239 kbytes of PSS on my testbed. That's why the access to the list fails at some point during iteration. Dynamic percentage calculation for the resolution of what should be displayed should fix this issue. A trivial patch which addresses the issue for me (please consider asking upstream about it, it's really just a quick hack that upstream might want to check/modify/improve): @@ -495,8 +495,7 @@ unused = tm - s t = 0 c = 0 - job_percentage = max(values) / (tm * 1.0) - while values and (t + values[-1 - c] < (tm * job_percentage) or + while values and (t + values[-1 - c] < (tm * .02) or values[-1 - c] < (tm * .005)): c += 1 t += values.pop() If you want to reproduce the issue on your own you can grab a daily snapshot from http://daily.grml.org/grml-medium_sid/ and execute "kvm -k en_us -m 512 -k en-us -cdrom ./grml-medium_sid_2010*.iso" Just start X ('grml-x fluxbox' on tty5 for example) and execute 'sudo apt-get update ; sudo apt-get install smem python-tk python-matplotlib'. regards, -mika-
