thanks for reply
if they are used for sessions - should the quantity of files only increase or also decrease? I can see it is always increasing. If so, they soon will consume all the inodes.

After some googling i concluded that garbage collector for some reason was not working as expected. It just could not be that there are millions of unexpired sessions on a not so busy site. I deleted all the files manually and will keep an eye on that dir if it still is only growing.
