I keep getting this error:

Internal limit exceeded in FixedSimpleVector
Fatal error in renderer: A POV-Ray internal nesting limit was reached.
Render failed

What does this mean?

I am using a loop containing a lightsource in a loop with media.

I can post the file if needed.

Ok, a bit more information...If i just render the scene normally, no issue. But
when I select a subregion, I get the error. I'm not sure, but this sounds like a
bug.

You've hit a hard-coded internal limit within POV-Ray. This limit is
there as a trade-off between performance, memory use and flexibility.
I don't like it but it's difficult to fix without impacting rendering
speed.

The error message itself should be fairly self-explanatory, though I
think we might need to add a reference to a doc page that makes the
issue clearer (in terms of what you can do about it).

Gotcha. As a developer, I can relate to how those things go sometimes.

It is, in that it effectively relates that a limit has been reached, which is
just about all its supposed to do. I agree that a docpage reference would be
nice.

Thanks for the info!

Although, it is unexpected that simply changing the number of decimal points I'm
dividing the size of a sphere by would be enough to also trigger this message.

(glowRadius / ((j * j) * 0.01))   //no error
(glowRadius / ((j * j) * 0.0001)) //error

Added a note and link (2nd paragraph) of the Light Sources section:
