[OSM-talk] High load on the rendering servers?

[Andrew Guertin]

For the past few days, lots of things I've changed haven't had their 
tiles re-rendered, and I noticed that the servers are reporting very 
high load and lots of dropped tiles: 
http://munin.openstreetmap.org/renderd-week.html

Based on my (completely uneducated) reading of the graphs there, it 
looks like something is filling the Priority Request Queue and keeping 
it full, and there's very little time for anything else. (It looks like 
the Request Queue and the Low Priority Request Queue are also being kept 
full).

Anyone know what's causing this?
