[Bug 876387] Re: fuser forking uncontrollably in cron job

[Graham Poulter]

My workaround is to restore the php5 cron job from 11.04, which does not
call fuser:

This is the 11.10 cron job:

09,39 *     * * *     root   [ -x /usr/lib/php5/maxlifetime ] && [ -d
/var/lib/php5 ] && find /var/lib/php5/ -depth -mindepth 1 -maxdepth 1
-type f -cmin +$(/usr/lib/php5/maxlifetime) ! -execdir fuser -s {}
2>/dev/null \; -delete

And this is the 11.04 cron job:

09,39 *     * * *     root   [ -x /usr/lib/php5/maxlifetime ] && [ -d
/var/lib/php5 ] && find /var/lib/php5/ -depth -mindepth 1 -maxdepth 1
-type f -cmin +$(/usr/lib/php5/maxlifetime) -delete

We think fuser was added to cater for some edge case of process not
closing the session file, but was never tested with a large number of
sessions.
