[Bug 802565] [NEW] Arbitrary file limit in garbage-collection cron script causes loss of service

[Chris Fryer]

Public bug reported:

PHP in Ubuntu 10.04.2 LTS includes /etc/cron.d/php5:

 09,39 *     * * *     root   [ -x /usr/lib/php5/maxlifetime ] && [ -d
/var/lib/php5 ] && find /var/lib/php5/ -type f -cmin
+$(/usr/lib/php5/maxlifetime) -print0 | xargs -n 200 -r -0 rm

$ dpkg -S /etc/cron.d/php5
php5-common: /etc/cron.d/php5

if your server generates PHP sessions faster than they can be deleted by
the cron job, the disk on which /var/lib/php5 is located will run out of
inodes, and thence to a loss of service.

It is caused by this upstream workaround:

The latest version of the cron job that does PHP session garbage
collection is here:

php/php.git;a=blob;f=debian/php5-common.php5.cron.d;hb=HEAD

This is related to Bug #316441 and Bug #482720
