 Replying to [ticket:29775 rudybrinkman]:
 > Anyway -- here's what happens: with a clean, no plugins added, install
 on a server with 8GB Ram, CloudLinux, Apache 2.x, up to date MySQL when
 you click on the media-manager it starts loading (rotating icon). And it
 keeps doing that. No images shown, uploading of images doesn't work (no
 error message) but in the mean time, the server runs wild. The proces runs
 something with 'ajax' and makes the server bog down (load up to 20.0,
 stopped it by restarting apache).

 I think this issue **may** be related to #29566, which was fixed in
 [29724] and resolved my version of this issue that I noticed today in
 WordPress 4.0 when I had orphaned attachments. A PHP Notice was breaking
 the AJAX response even though a successful query was being returned. I am
 not sure about the server load issue you're seeing, but it's probably
 worth a shot.

 > Uploading new images of files doesn't work either. It shows broken
 images or a blue 'image' that can't be inserted in the posts or pages
 (button not enabled).

 I'm not sure if this relates or is something different. If an attempt was
 made to upload an image while the previous AJAX response was broken, I
 could see it having issues.
