Hi,

  it seems this bug or its cause is removed in version 0.6.8 of dstat. See Changelog: http://svn.rpmforge.net/svn/trunk/tools/dstat/ChangeLog

"- Removed complex process name since /proc/pid/cmdline behaves different on new kernels (Adrian Alves)"

 They removed problem causing lines from dstat_topcpu.py and dstat_topmem.py.

Regards

Reinhard

I cannot reproduce this with 0.6.9svn:

$ dstat --noupdate -M topcpu -M topio --all --load 20 6

Fixed even earlier upstream in what is already committed in Jaunty, but not Intrepid.
