[Zope] Problem with Photo Folder

[David]

Hi

Zope 2.7.5 / Photo & Photo Folder product version 1.2.3 / Python  
2.3.5 / Solaris 8 Intel

We experience problems generating "displays" with the default  
settings on files larger then 650K. Uploading images works fine and  
the thumbnail is created. We had the setting of creating displays on  
uploads initially off, assuming these would be created on demand.  
Changing the default did not help and created the same error. (see  
example traceback below from the initial error)

We are using the ZODB for storage and ImageMagick as the engine. We  
had problems compiling PIL on Solaris 8 and installed ImageMagick  
using the Sun-Blast packages (pkg-get).

We monitored the machine playing with smaller and larger images, but  
could not see any noticeable increase in CPU or memory usage. Where  
is here the bottleneck and how can we change it?

Any help welcome! (Googling "popen2" did not help either.)

Cheers

DR
