Carrara 8.5 is a memory-eating zombie from hell (apparently)
This is one for the techies, I think. Anyway, it's got me baffled, which admittedly is not too difficult.
I'm running an iMac with OSX 10.7.5, 4GB RAM.
After numerous hangs with the new version of 8.5, I used Activity Monitor to try to see what was happening. Most of the system report detail is incomprehensible to me, but I concentrated on three things:
Real memory use
Virtual memory use
Any figures below are in that order.
open Carrara: 3.5%, 85.6MB, 70.7MB
new empty file: 1.0%, 126.0MB 115.7MB
which seems reasonable.
close new file: stays the same
open big file (33MB, terrains, shaders - ran fine on the beta version I was using, 179 I think)
100% 1.95GB 3.17GB
The memory figures then increases slowly, with me doing nothing at all to the set-up. The spinning beach-ball of death appears, Activity Monitor says Carrara is "not responding".
For the next five or so minutes the CPU value wanders about between 1.9% and 60%. The memory figures increase to peak at 2.5GB and 6.19GB, there is less than 20MB free system memory. Tense, huh?
I hold my nerve as the Mac shakes and glows cherry red (well, not really). The CPU figure goes to 99.6%, the memory figures drop to 1.08GB and 1.09GB, and Carrara starts to respond again.
Values then fall back to 0.9%, 92MB, 1019MB, and things work until the next hang-up.
Clearly this no way to get things done. As ever, all suggestions gratefully received. Thanks.
