extensive number of session files #29
Description
Hi, I would like to report an issue with your docker image. PHP is creating extensive number of session files. Looks like it creates ~1 file per second, this goes to GBs and hundreds of thousands of files created which are not being cleaned up. I'm using your image without any modification. Adminer was installed through rancher UI on rancher OS through community catalog /env/1a5/catalog/community:adminer?catalogId=community.
