Ben,
could you try replacing the standard cron-job with this script:
-- cut here --
#!/bin/sh
# first find all used files and touch them (hope it's not massive
amount of files)
lsof -w -l +d /var/lib/php5 | awk -e '{ if (NR 1) { print $9; } }'
| xargs -i touch -c {}
# find all files older
Also happening here.
- Ubuntu 12.04.1 64-bit
- PHP 5.3.10-1ubuntu3.4 with Suhosin-Patch (cli)
- psmisc Installed: 22.15-2ubuntu1.1
Unsure how to list versions of other PHP packages, but happy provide
more information if needed.
As a temporary fix, I have removed the fuser part of the cron job

From the Debian bug discussion, this appears to be a problem with psmisc
and not really fixable in PHP5. So I'm going to mark this as Invalid for
PHP5, and Triaged for psmisc. It may be worth bringing in 22.15's fuser
into 11.10 to fix this, as I can't imagine php is the only thing that

periodically all my threads resources are getting exhausted, which leads
to faults in some programs

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) !
The fuser check was added to not delete still active session files (e.g.
created long time ago, but still actively used by php5 process).
