[PD] pd / crash problem

[henning m. lederer | visual communication & animation]

Hi Chris.
Thanks a lot for your ideas. I gave it a try and Apple Intermediate and 
PhotoJpeg are definitely better. I didn't know that the Animation codec 
is using Perian. Okay: The current running time is now about 2 til 3 
hours! The CPU is at about 40% … But it crashed again. The Physical 
Memory and the Virtual Memory (sorry, I used a wrong translation before) 
are still increasing… slowly, but steady. When it reaches more or less 3 
GB (2,98 GB physical memory) and about 4 GB (3,95 GB virtual memory) the 
app crashes again. This time completely with no report at all.

Is there any way to empty this cache within pd? Or why is it doing that 
at all?

Any help would be great! Thanks a lot so far.

Henning
