I'm using the PVE 5.2 test cluster on HP Proliant DL-160G6 servers. I recently updated the kernel to one of the kernel nodes before the version of pve-kernel-4.15.17-3-pve and I had problems with the network.

Network cards:
Code: 
05:00.0 Ethernet controller: Intel Corporation 82576 Gigabit Network Connection (rev 01)
        Subsystem: Hewlett-Packard Company NC362i Integrated Dual port Gigabit Server Adapter

        Capabilities: [160] Single Root I/O Virtualization (SR-IOV)
        Kernel driver in use: igb
        Kernel modules: igb

Network settings:

Code: 
auto lo
iface lo inet loopback

iface enp5s0f0 inet manual

auto enp5s0f1
iface enp5s0f1 inet static
        address  10.0.100.1
        netmask  255.255.255.0
        post-up ifconfig enp5s0f1 mtu 9000

auto vmbr0
iface vmbr0 inet static
        address 172.16.1.2
        netmask 255.255.255.0
        gateway 172.16.1.1
        bridge_ports enp5s0f0
        bridge_stp off
        bridge_fd 0


The interface enp5s0f1 looks towards the cluster network ceph and for the performance increase the transmission of larger frames is enabled.

After updating the kernel to pve-kernel-4.15.17-3-pve_4.15.17-12 on the interface, the RX errors counter began to grow and when executing ethtool -S enp5s0f1 I see the error growth at rx_length_errors. And also when executing

Code: 
# pvesm status
got timeout
Name         Type     Status           Total            Used       Available        %
local         dir     active        28510260         2208896        24830084    7.75%
rdb           rbd     inactive            0               0              0        0%

And also when doing. In the log files, persistent messages

Code:

Return back to version pve-kernel-4.15.17-1-pve_4.15.17-9 returns the system health.
