Strange. I tried to reproduce this error with the current release branch
(6.4.svn) and with trunk on a laptop with Fedora Linux 16 64bit, Intel
core i5 at 2.4 GHz and 4 GB RAM.
I followed this tutorial:
http://qgis.spatialthoughts.com/2012/07/tutorial-making-heatmaps-using-
qgis-and.html
and used this dataset:
http://data.london.gov.uk/datafiles/crime-community-safety/police-uk-
crime-data-surrey.zip
with region settings:
g.region n=318266 s=117316 e=593618 w=363772 res=100 -p
No success, i.e. v.kernel finishes successfully in a reasonable amount of
time:
{{{

I suggest to update to GRASS 6.4.3RC1.
