I am trying to determine why my management interface on a Cent7 box goes down after about an hour or so consistently. I have to bring a crash cart into our server room to ifdown eno2 && ifup eno2 to bring the interface back online. Has anyone seen this before? Here are the log entries that NetworkManager is showing at the time of the interface going down.

journalctl -u NetworkManager :

Aug 13 16:01:01 slc-serv-01 NetworkManager[1336]: <info>  [1565733661.6495] device (eno2): state change: activated -> deactivating (reason 'connection-removed', sys-iface-state: 'managed')
Aug 13 16:01:01 slc-serv-01 NetworkManager[1336]: <info>  [1565733661.6502] manager: NetworkManager state is now DISCONNECTING
Aug 13 16:01:01 slc-serv-01 NetworkManager[1336]: <info>  [1565733661.6609] device (eno2): state change: deactivating -> disconnected (reason 'connection-removed', sys-iface-state: 'managed')
Aug 13 16:01:01 slc-serv-01 NetworkManager[1336]: <info>  [1565733661.6732] manager: NetworkManager state is now DISCONNECTED

I will post more configuration settings tomorrow once I have access to the box again. Any ideas are greatly appreciated!!
