My settings (diff from the original Ubuntu PPA: ppa:brianmercer/php)

---------------------------
pm.max_children = 24
pm.max_requests = 10000
rlimit_files = 32768
---------------------------

I am running the server for more than 10 days, memory grow slowly from
200MB initially to 400MB now, do you think there are possible leak of
the php5-fpm?

Anything to trace/debug?

Thanks,
