nginx eating all RAM, log files?

[Richard Kearsley]

Hi
Are you sure it's not the linux file/buffer cache that's using all your 
ram? (does ps/top show nginx or the worker processes using it directly?)
Linux and most/all other unix variants will fill up unused ram with 
cached versions of the most recently used files so they don't have to be 
read from disk each time... it's completely normal and expected behaviour :)
