Catalog Generation Error

In the last couple of days, I have suddenly had an error when trying to generate a catalog of my library in MOBI format. I am running Calibre v 0.8.58 on Windows 7 Pro x64 with 6gb RAM. I "think" it is a problem with the # of books (~7000) because I can generate a catalog of a library that only has ~425 books in it.

Here is the Error Message (I cut out the Titles, Genres, Chapters and other similar items to shorten the message):

Any ideas on what my problem might be?

'MemoryError' is a strong clue.

Even if you could build a catalog that big, it wouldn't be very usable on a kindle, if it would even load.

I'd suggest subdividing your library into smaller chunks for cataloging.

I would agree, but what is interesting, is that it worked with 100 lesss books without any issue at all.

You apparently found a breaking point.

I recall that when the catalog code was first released, someone built a working catalog with about 3500 books. It seems that you've set a new high-water mark.

Hardly . I can create an EPUB format catalog of my library (with just Title and Author, though), which has almost 50K books in it.

I can't create a Mobi format one, though; that starts eating memory until it hits the 2GB process limit and blows up.

I hadn't thought of trying EPUB... I switched to MOBI a couple of months ago to see how that worked, and didn't think about that being the issue. I'll give EPUB a try and see if that works.

Thanks,

Eric

Tried the EPUB and it worked. Thanks for the tip.
