<DIV><FONT size=2 face=Arial>Hi Josh,</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>It seems highly probable that RVIZ was killed due
to memory usage. I ran a long test this morning, after having rebooted my
computer and the robot, and RVIZ did not crash but it's memory usage was every
increasing. It started at 25 MB and after 15 minutes was at 100 MB. It seems
like the more movement there is in the image, the faster the memory
increases.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>I'm going to upgrade to c-turtle and see what
happens.</FONT></DIV>

<DIV><BR></DIV>rviz's Camera display is meant for a camera running on a robot
that's set up properly (with TF, calibrated cameras, etc.). It lets you
see the 3D data with the camera image overlaid. If you just want to view
an image, image_view is the correct option.
<DIV><BR></DIV>
<DIV>As for #3, does rviz's memory usage start going up during that time?
If it was killed, either it (or something else) was consuming a lot of
memory, or someone else killed it.</DIV>
