The CPU load could be caused by file system watchers that try to
detect whether the application needs to be recompiled/reloaded.

You're using a quite old Mono version on an unknown operating
system, so it's hard to tell if this is a bug or just by design.

Set the env var MONO_MANAGED_WATCHER=disabled and check
whether the load is still present.
