Hi, I've tried to post this once, but it seems I was logged out during writing, so I don't think it posted. Apologies if it did as this will largely be a duplicate.

I'm trying to convert an epub file to AZW3 and it failed. it first hung at 47% and I let it run through the night and it crashed after 11 hours. In the detailed log there was an error Message: Python function terminated unexpectedly (error code 1), it continued running and failed terminally With a memory error.

My computer is a 64bit Windows 10 machine With 16gb of RAM.

I then ran book check and there were over 200 errors related to the CSS Construct not being recognized.

The book is a 42GB Seientific book With many formulas.


I'm in Contact With the Publisher. Any idea what might be wrong?


The bottom part of the detailed Conversion output file is below:

Merging user specified metadata...
Detecting structure...
Flattening CSS and remapping font sizes...
