Crash message

[andystopps]

Here's a new error message I haven't seen before, does anyone know what might have caused it ?

Error: DB 0.2 fatal 041264: Release Semaphore failed - the handle is invalid.

This showed when I drew a render region. A piece of geometry had just failed to appear in a render region and I re-drew it. Needless to say, I didn't do the sensible thing and Save first...

It is probably a memory problem.

Is this a heavy scene? Do you have a memory limit set for mental ray?

No, it's pretty light at the moment, around 170,000 triangles. I didn't have the memory limit set though. I haven't set the 3GB switch either, because I'm using Vista (32 bit), and the Microsoft info seemed to suggest that it doesn't really do anything now (is this correct, or should I set it anyway ?).

[StephenBlair]

On Vista there is no boot.ini and so no /3GB switch.
You would set IncreaseUserVA with Bcdedit (http://blogs.technet.com/brad_rutkowski/archive/2006/10/03/Hey-where-did-_2F00_3GB-go-in-Longhorn-and-Vista_3F00_.aspx).

oh, yes, I'd forgotten about that. I tried it when I first installed Vista, but then switched it back when Vista put up some memory-related blue screens (actually down to inferior memory modules, but that's another story).
Thanks Steve, I'll keep an eye on it (though there hasn't been any recurrence of the problem).
