I had a similar issue to Phil. A web server was generating PHP sessions faster than they were being deleted by the cron job. This caused the disk on which /var/lib/php5 was located to run out of inodes, and thence to a loss of service.
It is caused by this upstream workaround, which is poor: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=461755#20 The latest version of the cron job that does PHP session garbage collection is here: http://anonscm.debian.org/gitweb/?p=pkg- php/php.git;a=blob;f=debian/php5-common.php5.cron.d;hb=HEAD It would probably be a good idea to backport to this LTS release, because it fixes Phil's issue, among other security concerns. ** Bug watch added: Debian Bug tracker #461755 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=461755 -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to php5 in Ubuntu. https://bugs.launchpad.net/bugs/316441 Title: PHP session garbage collection To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/php5/+bug/316441/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
