Hi,
> Somebody above suggested that I use Batik instead of Inkscape - well,
that doesn't work at all and fails with an error message about some
missing file in the lib directory. Anyway, I assume, I'm not alone with
my Inkscape-related trouble. How about somebody throws together a small
script that monitors the cpu-time of running inkscape sessions and kills
them off after a certain amount has been used? I've just come home again
to find tah hanging due to an inkscape error. The machine hasn't been
very productive during the last two days because of that.
Well. I have a small program in C which does that. It starts the command
with the arguments provided and kills it after a limit (selectable at
compile time) is reached. IT has two major downsides though. It needs a
one line patch to the tilesathome client and it has to be compiled on the
system running the client which makes it way less portable then the perl
scripts. So if at all possible we should find the underlying problems with
inkscape...
HTH,
Patrick "Petschge" Kilian
