Yeah, DR render stuck on “cleaning up”. Looking for the “go un-stick” button. 2.5h cleaning (and going) after successful 5000pix render.
Corona 1.7 (host and farm).
Help appreciated

Even if that does not help: You are not alone… Had this one time but was so upset that I forgot to shoot a minidump from that state. But I fear the problem is max - not Corona.
Good Luck
Is it Corona 1.7 or 1.7 hotfix 2? 
Also, a minidump generated from a freeze like that would probably help. Please generate it next time it happens: https://coronarenderer.freshdesk.com/support/solutions/articles/5000524006
