Question #228762 on Graphite changed:
https://answers.launchpad.net/graphite/+question/228762

Description changed to:
When I've started up all necessary processes for graphite:

/opt/graphite/bin/carbon-cache.py --debug start
/opt/graphite/bin/run-graphite-devel-server.py ../
/opt/statsd/node stats.js localConfig.js

And open: http://127.0.0.1:8080 everything looks just fine (a gray
graphite bar on top, I can create and login with a account). However as
soon as I open "Dashboard" section the process: run-graphite-devel-
server.py just stops (without any message).

Running run-graphite-devel-server.py with strace -f | tail -n 50 shows me this:

I have no idea how to trace this back to anything useful and some help
would be much appreciated!
