VTN Crashes, does not recover

[J-L]

Perhaps this is a configuration issue, however the VTN runs, and the it seems like it times out. Subsequent requests are responded with 'Something went wrong' and errors like this in production.log

I too have this issue it appears to be something wrong with the loading of the navigation bar. From my own testing wrapping the link_to in app/views/application/_naviagation_menu_item.html.erb with a begin rescue NoMethodException and doing nothing with the exception keeps the app running. The downside is when the exception does raise the navigation bar does not load however typing links in the address bar appears to work. I will do some more testing.

Note I'm using Java7
