Description of problem:
Hello,
This error occured when restarting munin-node service after enabling fail2ban module (ln -s /usr/share/munin/plugins/fail2ban /etc/munin/plugins/fail2ban). I am using fail2ban-0.9-2.fc20, munin-node-2.0.21-1.fc20, selinux-policy-3.12.1-182.fc20.
Thanks to solve it
SELinux is preventing /usr/bin/python2.7 from 'ioctl' accesses on the file .

*****  Plugin catchall (100. confidence) suggests   **************************

If vous pensez que python2.7 devrait être autorisé à accéder ioctl sur  file par défaut.
Then vous devriez rapporter ceci en tant qu'anomalie.
Vous pouvez générer un module de stratégie local pour autoriser cet accès.
Do
autoriser cet accès pour le moment en exécutant :
# grep fail2ban-client /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
