Machine Vision
Insufficient transfer engine resources error
Great thread! 
With some time between LabVIEW vision jobs, I'd forgotten about the problems I encountered with multiple cameras on the last job.
For this new project I'm once again using Fire-i 1394 cameras. Four in this case.
Because I need this one to "feel" more responsive to the operator, I need to have sessions to all four cameras already opened so that when an inspection request was made the image hit the screen right away. But this morning when I tried some new code, I was getting the error.
In my case I was able to adjust the Video Mode for my cameras from 30fps to 15fps. This cut my packet size down to 640 per camera, bringing me under the maximum for four. +5 for the answers on this thread!

Hi Carlton,
I am running XP SP2. But I didn't see the 100MB bug. All four of my cameras set themselves to 400MB.
Since I'm only Grabbing a couple of images, the speed that I'm grabbing at doesn't really matter. So I just dropped the speed of cameras in MAX to 15fps from the default of 30fps. This lowered the bandwidth for each camera by half and meant four of them would fall under the limit.
Technically I should be using the Snap utility in this program. But it's never worked well with the Fire-i cameras for me, even with the "Ignore first frame" box checked in Max. What I've got is working for me so far. Now I'm just waiting for my first meeting with the customer where I learn I have to change everything.
Thanks for the feedback.
