Mono MVC4 + Web API single page application is running in Debian with
mod_modo.
Refreshing browser window several times by pressing Chrome Refresh button
causes 500 errors returned from server. Those errors occurs occur randonly

For those requests apache error.log contains `Failed to map path` errors (
file is below) .
