PHP Sessions causing Error

Currently your messages log is filling up with errors and the system is unstable. Check the message log:

$ server# tail -f /var/log/messages
Jul 28 08:57:30 mail kernel: EXT4-fs warning (device sda3): ext4_dx_add_entry: Directory index full!

Check the sessions directory

 $ server# php -i | grep session.save_path
session.save_path => /var/lib/php/session => /var/lib/php/session

$ server# du -shcx /var/lib/php/session
1000.0M    /var/lib/php/session
1000.0M    total

A cron job similar to the following ran every day, or periodically, should prevent those files from accumulating.

# find /var/lib/php/session -type d -mtime -15 -delete


# find /var/lib/php/session -depth -mindepth 1 -maxdepth 1 -type f -cmin +120 -delete;
