Bug#442038: server crashes when lauching /usr/share/mdadm/checkarray --cron --all

[Jérémy Lal]

Package: mdadm
Version: 2.5.6-9
Severity: important

I noticed that because the server began to crash every day since 3 days...
I found the command in /etc/cron.d/mdadm to crash immediately the server.
i didn't find any log of that crash. The server just doesn't respond any more, no ping, ssh interrupted.
For now i just disabled the /etc/cron.d/mdadm script, i'll see tomorrow if it still crashes or not.
I don't get any messages from mdadm and nothing strange about raid in syslog.
