We are using Concrete version 5.6.3.3. Our website was down this morning and we found these errors in the log:

We aren’t able to view the files located in the /var/www/files/tmp folder via either Webmin file manager or directly through command prompt at the server. We’ve shut down the server and restarted again and the website is running but it hasn’t cleared out this folder (/var/www/files/tmp) which is over 1 gigabyte. Is there a recommended way to remove the unnecessary files or clean up this folder?
