WebUI 500 errors

Chef Infra (archive)

Hi chefs!

A few of my users have been complaining about timeouts from the UI. I
have yet to repro this myself, but i did happen to catch the webui log
while someone was complaining they were having issues.

heres the log output
http://pastie.org/4167984

its not obvious to me why its returning nil on the nodes controller
and any subsequent requests to the UI work just fine. anyone have any
ideas?

Maybe. But i dont see anything wrong happening there either. When I
make a request agains /nodes everything seems to work fine. Its a
little slow, but never times out. As you can see here

Ok, I'm pretty sure that this is being triggered in the UI by asking
for all nodes. If i specify and environment and this request nodes
everything is quick and displays properly. If i change environment to
'none' it will eventually time out.

Look for a node with a name of 'null' within your couchdb interface and
rename it or delete it. I've had a similar error with our installation
before.
