Hallo,

ich habe Proxmox auf einer Mini-Firewall Appliance laufen.

Hier kurz die basic Infos:
CPU(s) 4 x Intel(R) N100 (1 Socket)
Kernel Version Linux 6.5.11-8-pve (2024-01-30T12:27Z)
Boot Mode EFI
Manager Version pve-manager/8.1.4/ec5affc9e41f1d79
Underlay ist ein Debian 12.

Am Anfang lief die Kiste reibungslos und performant. Eine VM ist am laufen, welche 1,6 GB RAM im durchschnitt nutzt und ca. 1,5 % CPU

Nach ein paar Tagen, sind jedoch Anfragen auf das Webinterface von Proxmox / das Webinterface auf die VM extrem langsam geworden.
Teilweise lädt das Webinterface für mehrere Minuten gar nicht und läuft in einen 'Connection Error - Timeout'.

Ich habe pveproxy pvestatd pvedaemon schon neu installiert, danach lief es wieder für wenige Stunden performant - anschließend wieder nicht.

Folgende Logs spammen die ganze Zeit das Logfile voll - alle 1-3 Minuten.

Code:

Auf der Debian Shell sehe ich alle paar Minuten folgende Meldung:

Code: 
Broadcast message from root@homeserver (Thu 2024-02-22 10:45:54 CET):

The system will suspend now!


Hier noch mein [I]/etc/network/interfaces[/I]

Code: 
source /etc/network/interfaces.d/*


auto lo
iface lo inet loopback


iface enp1s0 inet manual


iface enp2s0 inet manual


iface enp3s0 inet manual


iface enp4s0 inet manual


auto vmbr0
iface vmbr0 inet static
        address 192.168.178.251/24
        gateway 192.168.178.1
        bridge-ports enp1s0
        bridge-stp off
        bridge-fd 0

Lustigerweise läuft die VM performant nach der anfänglichen langen Ladezeit.


Hat irgendwer eine Idee?


Edit: Ping / XRDP zum Debian läuft während dieser Aussetzer und Timeouts auf dem Webinterface übrigens ohne Probleme durch.
Ipferf Messung zum Debian kommt auch auf dauerhafte 800Mbit.


Viele Grüße

Daniel
