max open files

Hi All,

just witnessed a website crumbling due to Varnish hitting the 
max_open_files limit (ulimit -n). After that I had the following 
hypothesis I want to check with you.

When Varnish hits the _max_open_file limit it starts to put servers in 
unhealthy state due to it not being able to open network sockets since 
network sockets are also open files.

Is that a correct assumption?
