in my phpInfo i see that the session save path is /var/lib/php5 this directory gets filled with empty files with names like:
"sess_fgf5gh2prbmnfs0ah3mcvpv4p4"
i am not using any sessions on my server. is this php default behaviour?. this is a problem because this folder needs to gets cleaned every 30 minutes by php and should it takes too much resources.
