/var/lib/php/session cleanup

We are running the FreePBX distro 3.211.63-8 with Asterisk 11.3.0

I recently noticed that we have thousands of files in
that should be cleaned up either with the php GC mechanism or a cron job. Is this something that’s setup in the distro or do I need to write my own job?

Has anyone else seen this with the FreePBX distro? If the files are never deleted it could eventually become a problem.

PHP does this automatically and randomly by default.
