On a "CentOS release 6.2 (Final)" server (with Ruby 1.9.3 and Rails 3.2), and using more memory than expected.
Looking at passenger-memory-stats I see a couple of HUGE httpd processes... any thoughts on how I can figure out what's going on and reduce the memory usage?
Stats are included here... thanks!
