odoo 10 enterprise, ubuntu 16.04

I am not getting any errors in odoo.log

The pdfs creation has only text, and takes a very long time to open. Cant figure it what can be causing it.

It was working yesterday and when I came in today it was no longer working. It happened a few days ago restarted the server a few times and it worked. But now I have restarted it 20+ times did updates nothing is working.
