ISPCFG3 + nginx + LXC => running into problems

I'm busy migrating a physical server to a LXC container and am running into the problem that when I resync ISPCFG3 I immediately get 2 emails:

So I used sdiff to see the differences between somedomain.com.vhost and somedomain.com.vhost.err and found it was these lines:

Code:

sdiff /etc/nginx/sites-available/somedomain.com.vhost /etc/nginx/sites-available/somedomain.com.vhost.err

server {                                                        server {
        listen *:80;                                                    listen *:80;
                                                              >     if ( $is_bot ) {
                                                              >         return 444;
                                                              >     }

So I thought, ok, lets remove them and resynced again. And again I get the nginx restarting problem email but now there is only one line of difference:

So now I have no idea where to start looking.

I looked through all logs but can't find anything related:

Code:

grep -R -i 'nginx' /var/log/ | grep bus

yields nothing. And yet nginx runs just fine. Even when restarted manually via command line i.e. /etc/init.d/nginx restart all is good, no errors whatsoever.
Please ask any questions you think might relevant I'll be happy to share more info about the server.

 

I have got some leads, is ISPCFG3 by any chance running systemctl when resyncing? 'cause there seems to be some problems inside LXC containers :-(

 

I'm running proxmox and found a thread in their forums saying

- is this related? Does ISPCFG3 need that or am I following the completely wrong lead here?

Hm, somehow I ended up having systemd inside my LXC. Have removed it now and am analyzing to see if anything broke
