Serverausfall bei S4Y, DHCP?

Guten Morgen Community,
am vergangenen Wochenende ist einer unserer S4y-Server (CentOS, Plesk) ausgefallen. Ich konnte ihn nur durch Hard-Reset wiederholen. Aus dem Log werde ich nicht ganz schlau, im Gegenteil, es wirft weitere Fragen auf:

- Wieso ist eth0 standardmäßig auf dhcp gesetzt und nicht auf static? Hat das einen administrativen Grund bei S4Y oder kann ich das auf static ändern?`

- Wieso kommen Die DHC-Lease-Renews im 15-Minuten-Takt?

- Wieso kann die Lease plötzlich nicht mehr erneuert werden (Nov 28 19:17:03 web04 dhclient: No DHCPOFFERS received.). Das war wohl der Ausfallgrund.

Es wäre Klasse, wenn mir jemand ein paar Infos geben könnte:
