Conversion Memory Error

Heretik · 08-30-2011, 08:46 PM

I have tried to convert this file from MOBI to Epub several times. It is a large file. It looks as if there is a memory overload when the process gets to converting to epub. I am including the mobi file and the log if anyone has any suggestions. Thanks.

Moved to correct subforum.

MemoryError implies that the conversion ran out of physical memory (RAM). There's no fix except to upgrade your computer.

The log file is incomplete. It was still processing and didn't have any error indicated in the log.

I didn't run out of ram. I have 4GB of ram. There comes a point during the conversion that the ram usage just begins to escalate at what looks like 100MB a second. Then the conversion fails. I get an error box.

As for posting the book, I did that because I read a similar post where the moderator said he would have to look at the file to be converted to figure out the problem.

You ran out of RAM...

If you do need to send Kovid a copyrighted book to analyse a problem, you do so by attaching it to a report on the bug-tracking system on his site. You do not upload it to a public site like this where anyone can download it.

You can fix this error by going to EPUB output int he conversion dialog for this book and telling calibre to not split on page breaks and increasing the split files larger than to some very large number like 400000

But note that the resulting epub will likely not work on some devices.

Thanks, Kovid.

Once you get it converted, you can try a EPUB->EPUB convert with smaller sized splits

or

you can Use Sigil on the EPUB and see if it will allow you to split up that big chunk

once you get it converted. (note: Sigil has no segment file size indicator. Guess from the size of the scroll bar / Split in logical places.

Then use Tweak EPUB in Calibre to explode the book and just look at the file sizes in the Text folder, then cancel-out of tweak.)
