too many sites, change server_names_hash_max_size?

[Payam Chychi]

Hey,

I dont think this is because of nginx, linux tends to utilize your RAM
regardless of what your running (may or may not be performance
impacting...)

I recently came a cross the same issue and after much reading it
turned out to be the behavior or the OS and not the application
