‘ ERROR : FATAL: DB 1.0 fatal 041500: interrupted by exception code 0xc0000005 (access violation)

The exception code 0xc0000005 (access violation) indicates this is probably a memory access error. The software is trying to access a region of memory that it shouldn’t be accessing. In general, this could be a problem in the code (for example, a NULL pointer), faulty RAM, or even a bad device driver.

If you get this error with any scene (for example, with one of the sample scenes that ships with Softimage), then that may indicate the problem is specific to your computers. Or if you get the error only with a certain computer, that would indicate a possible problem with that one computer.

If you get this with just some scenes, then that points to a problem in the software (or perhaps the scene). It could be that something about the scene triggers certain conditions in the software, and the software then causes the error. In general, I would try breaking down the scene to try and isolate the root cause. It could be the overall complexity of the scene, or a specific element of the scene.

In one case I had recently, the user got this 0xc0000005 (access violation) error and then an endless series of bad message…0xbad0bad errors. We traced the access violation error back the number of different animated objects that were being instanced through ICE using assemblies.

Assemblies are used when an ICE trees use one of these compounds:

  • Set Instance Geometry
  • Set Particle Instance Animation Time
  • Control Instance Animation
  • Control Displacement Instance Animation

Using assemblies can be memory-intensive, so it appears that when you’ve got a lot of particles and a lot of animated instances of many objects, satellite rendering may fail with a memory access error (actually, the frame was rendered, but XSI was hung up after because of the errors).
