[OSM-dev] Tirex - Rendering jobs stucked in the queue

Thank you for this new perspective. I've had configured test renderer and 
example mapnik renerer style enabled before but since I was testing them after 
the queue was stucked by my mapnik style rendering requests, it was giving me 
the same 404 errors as my layer requests so I didn't notice they are actually 
working.

So this means that the problem is in my layer rendering inside the tirex-
backend-manager process execution. But since I've tested my mapnik rendering 
styles from genrate_tiles.py script as normal user where it's working, the 
problem may be related to rendering process executed as tirex user or by some 
unexpected issue that is relevant to tirex-backend-manager environment itself.

This leads me to a question: Is there a way how can I enable debug logging of 
tirex-backend-manager (and its mapnik rendering plugin) execution to see what 
is actually wrong?

The symlink is existing with the same permissions.
