Cleaning /var/lib/php/sessions - 100% inodes usage - Ubuntu 16.04

After having issues doing anything on one of my Ubuntu 16.04 droplets due to disc usage errors, I found that I was running out of inodes and there are about 6.2m of them in /var/lib/php/sessions.

I recently updated from PHP 5 to PHP 7, I think this has caused the issue.

My questions are:

What’s the best way to clean sessions from this folder to free up inodes?

How can I prevent this from happening again?

I have this

09,39 *     * * *     root   [ -x /usr/lib/php/sessionclean ] && if [ ! -d /run/systemd/system ]; then /usr/lib/php/sessionclean; fi

in etc/cron.d/php but it doesn’t appear to be working.

Hi there,

I believe that this is a good approach.

What happens if you try to run the script manually:


Do you get any errors?
