I'm going to guess PHP sessions. Off the top of my head its the only /tmp file creating thing I can think of in common web stacks.
If that is the problem mise is facing, you can swap out the storage that PHP uses for sessions (to use something other than files), I'd point out the relevant docs but I have a meeting to get to.
I'll look into this. My host Servint says that my inode allocation is "generous", so I wonder if I'm the only person running into this problem with PHP+nginx.
