I seem to be getting strange results here. I have a 300-frame animation
segment I'm rendering. Everything seems to go well until the render has
been running for a few hours (~5). Then, I see new error messages
appearing, such as:
--
Rendering frame 62 of 300
Scene contains 8978 frame level objects; 1 infinite.
05:13:21 so far, Possible Rendering Error: Cannot write PNG data.
Possible Rendering Error: Cannot write PNG data.
Possible Rendering Error: Cannot write PNG data.
Possible Rendering Error: Cannot write PNG data.
Possible Rendering Error: Cannot write PNG data.
Possible Rendering Error: Cannot write PNG data.
Possible Rendering Error: Cannot write PNG data.
Possible Rendering Error: Cannot write PNG data.
Possible Rendering Error: Cannot write PNG data.

However, frame 62 finishes normally (it looks fine), and then POV-Ray stops
rendering frame 63.
Strangely, if I restart the process at frame 63 (or even 62), things
continue along normally. No rendering error of any sort. Am I somehow
building up 'residue' from previous renders? Is there some way to 'flush'
this each time to start fresh?
Any light shed on this mystery would be greatly appreciated.

The 'Possible Rendering Error: Cannot write PNG data.' message usually
occurs if POV-Ray isn't able to write the image data to the disk. So you
might check if:
- disk is full
- you lost connection when working on a network drive

Aha, that may very well have been the case. Looking more closely, as the
next frame was attempted, POV told me it couldn't find my _input_ file.
Thanks, Christoph!
