Running function run_cron_script in Cloudmin GPL for KVM

Hi,

when i running in Webmin Scheduled Functions in Cloudmin 7.7 kvm on Debian wheezy: 3.2.0-4-amd64 #1 SMP Debian 3.2.57-3+deb7u2 x86_64 GNU/Linux

the run_cron_script with status.pl as parameter I obtain this messages:

Use of uninitialized value in split at /usr/share/webmin/acl/acl-lib.pl line 47.

Use of uninitialized value in split at /usr/share/webmin/acl/acl-lib.pl line 47.

.. done

and some message in syslog like:

Buffer I/O error on device loop0, logical block 2621424

at line 47 in acl-lib.pl I have this: ... foreach my $a (split(/\s+/, $miniserv{'logouttimes'})) { ...

What is the problem ?

Thanks
