Foreman » Smart Proxy

Hi,

one of my smart proxies stopped managing ISC DHCP after it tried to parse lease definitions:

lease 10.131.12.60 {
  starts 6 2018/01/06 11:51:30;
  ends 6 2018/01/06 23:51:30;
  tstp 6 2018/01/06 23:51:30;
  cltt 6 2018/01/06 11:51:30;
  binding state free;
  hardware ethernet 08:00:27:bc:8f:13;
}
lease 10.131.12.51 {
  starts 4 2018/02/22 12:24:37;
  ends 5 2018/02/23 00:24:37;
  tstp 5 2018/02/23 00:24:37;
  cltt 4 2018/02/22 12:24:37;
  binding state free;
  hardware ethernet 18:66:da:e7:83:55;
}

The error message is

If I manually edit the file and remove these example entries it's all good. Problem is that the very same DHCP server is used for nodes that are not managed my Foreman so I can't avoid lease entries popping in it.

I'm using Foreman 1.16 on CentOS 7.4. Smart-proxy is managed by latest Puppet manifests.
