We also found this problem: the PHP cron launches one fuser for each PHP
session file, and the process is never reaped (remains in <defunct>
state)
Workaround for PHP is to remove the fuser check, which was only added
11.10 anyway.
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
