Not working with large media libraries; tries to allocate large amounts of mem
-
As the subject says. A site with 43000+ media items tries to allocate several hundred megabytes of memory, even if only selecting a small subset of posts (~20 posts) to export. Specifially line 232 triggers this fatal error, and I believe the reason is that you load ALL media items into an array (line 81), rather than narrow that query down to only include relevant posts. In line 92 you know which posts are relevant for the query, why not use that to construct a much more optimized query?
This error is the same one that causes the ERR_INVALID_RESPONSE response as others have posted about.

Hi Uffe,
I’m afraid with such a large media library this plugin no solution.
The problem is that WordPress does not keep an index of which media are used in which post. So to get better results it searches all post content for all attachment URLs.
Even when you only export one post, you don’t know which of your 43k+ media is used in that post so we test for them all (inc. all media sizes WordPress creates).
That’s why on line 81 a list of all media is created and in the method of line 232 the list of all media URLs is created.
You might try to not to do the URL test (disable line 107 and lines 146 through 165) but I expect you will miss al lot of media in your export.
