Is there something I should do about it? Should I empty that folder
everyonce in a while? Do I risk crashing my FS? Or I should just leave
it be?

The easiest way to resolve this problem is to write a cron job that
removes every one or two houres files that are older than a certain
time. That way you are only keeping the most recent session files.
Another option is to store the sessions in the db and delete them
occasionally.
