In regards to ASP, try ImageMagick 6.4.1-8, the latest release. We have a patch in the ImageMagickObject COM object to fix a problem where the process was returning a status code suggesting the process failed when it didn't. We also recently fixed a thread race condition that was very rare but could occur over ten of thousands of threads of execution.
