plain lxc:
lxc-start -n dns -d
I am pretty sure it is not restarting.
e.g. an open shell session would be destroyed on a restart (lxc-attach)
The filesystem is not versionable to have access to the previous old
zone file.

This really sounds like the zone file is *in* the container itself,
and that the container is restarting.
You said that this is running under LXC -- is this actually a Docker
container? How are you starting the container?

I know.
So far, the only files changed are the ones I changed myself, like
bind config files and vimrc.
No hidden toolkit found too.
I still think that it is easier to be a misconfiguration done by
myself.
Still looking for better indications that this could be the case.

IP ports not open does not mean is not hacked.
a vulnerability can be used to make a change or an access
try to change and audit file access and permission firewall log
analisys can give a plus to find a solution (check all IP traffic
out from TCP/UDP 53)
If you have RNDC , change KEY or disable it

Sorry,
Static files.
It is the master server.
No dynamic updates.
Host under lxc with only bind ports open.

*Subject:* bind 9 goes rogue and revert zone information
Hello,
I have a very strange behavior that I am failing to understand.
2 to 5 times a week, a named server revert back to a previous
version os
a master zone.
This happens during the night, usually around 20h EST.
This zone has a serial of 3017020401
<tel:%28301%29%20702-0401> (yes, I typo the 3 somewhere in the
past).
When it reverts its zone information, it goes back to
3016060101 <tel:%28301%29%20606-0101>.
I have updated, restarted the host, clean all cache and
journal files,
grep all files in the host for 3016060101
<tel:%28301%29%20606-0101> (just shows up in the logs).
So, I have no clue why, or how it is happening. Where does it
get the
old information.
I thought first about the serial, but it would have happened
in the past
too, right? As it should be a 32bit unsigned integer, it
shouldn't be a
problem, IMHO.
Yet, when "dig domain -t SOA @server", it is there again.
The host is a debian Jessie and bind is 9.9.5,
1:9.9.5.dfsg-9+deb8u8
more specifically.
Thanks for any direction.

I don't think the execution is relevant when it was obviously a bad
idea in the first place.
This is like putting rabid weasels in your pants, and later expressing
regret at having chosen those particular rabid weasels and that pair
of pants.
