Duplicate Posts & Picture by creating user Posts with meta/custom fields

[my-fish]

Hello,
we have created a plugin for creating user posts as project with an edit function. The last two years it worked fine. Now, with the update to 4.2.2 we recognized a duplication bug. How it works? For post creation by a community user we use the custom fields to add meta data for the projects. After the update to 4.2.2 a new post will uploaded in a loop for the complete runtime. In the same way the media. So we got round about 100-150 posts and new media (all with an unique id). In the error log we can't find any problem tracked. Know we now the wp_insert_post infinite loop is the problem. The same post without any pictures can be created without any problems. Only the media / picture upload cause this duplicate problem.

If you want we can send the whole plugin code to you.
