I have a PHP 7.4 application that runs on Debian 9.13 Stretch.
If I run df -h I see the following result:
Filesystem Size Used Avail Use% Mounted on
udev 1.9G 0 1.9G 0% /dev
tmpfs 386M 39M 347M 11% /run
/dev/sda1 50G 9.7G 38G 21% /

tmpfs 5.0M 0 5.0M 0% /run/lock
tmpfs 1.9G 0 1.9G 0% /sys/fs/cgroup
If I run df -i it shows:

udev 491092 313 490779 1% /dev

tmpfs 494055 2 494053 1% /run/lock
tmpfs 494055 15 494040 1% /sys/fs/cgroup
I receive the following errors:
Warning: session_start(): open(/var/lib/php/sessions/sess_8ov813u743ic7skcp70j98m160, O_RDWR) failed: No space left on device (28) in /var/www/...
Warning: session_start(): Failed to read session data: files (path: /var/lib/php/sessions) in /var/www/...
Warning: session_regenerate_id(): Cannot regenerate session id - session is not active in /var/www/...
If I run the following command in the sessions folder:
ls | wc -l
It returns 134 as the number of files.
If I clear everything inside the sessions folder the errors disappear.
What can I do to prevent these errors? Should I change the session storage location? Should I make other changes in the php.ini file? Should I change owner/write permissions for the sessions folder?
