I'm using Calibre 3.7.0, KFX Output 1.10.0 and Kindle Previewer 3.13.0

I have an ePub that has a lot (twenty-ish) images in it, and I'm trying to convert using the KFX Output plugin. I keep getting failures after long runs with a lot of retries (e.g. retries after erratic conversion errors, per the detailed run output). The specific error that I'm seeing is this one:

ERROR: KFX conversion failed: <book name> Kindle Previewer error: Exception in thread "main" com.amazon.kcf.conversion.image.e.a: KindleImageConverter Failed with exit code : -1073741819error String: IMG_CONV_UNKNWON_ERROR

Note that "-1073741819" in decimal is 0xFFFFFFFFC0000005 on my 64-bit system, for what its worth. Other than the fact that "UNKNOWN" is misspelled in the error, there is no joy here.

Any insight into what is happening, and what I can do to tweak the ePub?

PS - I kept rerunning the converter, and eventually it completed without errors! As Emily Litella used to say, "Never mind..." Nevertheless, I would like to understand what is going on here.
