Well I was getting "Thumbnail tag failed" (but everything was working fine)
So according to : Thumbnail tag failed: (sorl-thumbnail 11.12)
I ran manage.py clear and then ./manage.py cleanup.
Ever since then, cpu has been choking and maxed out from the exact moment I ran those commands.
I profiled it and it was sorl thumbnail causing it.
How can I reverse this? I think it was the clear method
Am desperate here.
This was a bug in sorl thumbnail.
I had to update the pip package and it solved it.
