Hello!
I think i saw things like this on this box in the past and i always
thought that i screwed up myself.
Buy today i am sure it happened by itself and i have proof.
First, config:

Memory:16GB,
CPU: 8cores XEON
DISKS: RAID10 (4 disks)
The machines runs 4 jails. Everything is in the jails except NAMED.
Named is run on the root host (if i may say so) itself.
There is a zone file there which i changed last week.
Today in the morning i try to open a site and host name is not found. It
worked on friday.
I went to see the the zone file. IT WAS DATED 2010 !!!! I open it and
the serial number is
something like 201103021. I do all my serials using dates, so, while the
file date is 2010
the content is from 2011 and it sure does looks so.
Then i go to secondary zone (slave) on another server and there i find
the zone from last week.
I checked all logs and did not find anything special. The zone file
from 2010 just reappeared
from nowhere kill all the new changes.
As i said, i saw things like this in the past. It happened insides jails
and was related to files
for web sites and i thought that i and someone else messed up. No i
think i saw the same thing.
How, how the hell it is possible?
