Hi,

We have a small cluster with 3 nodes and 2 storage servers. The nodes are connected with a bond to 2 switches with LACP. Switches are in virtual chassis and have the port groups configured.

Recently we started to see network errors/hickups. They only seem to apply on the proxmox servers, other network traffic isn't affected.

I upgraded Proxmox to 5.3 but the issue is still comming back every week:
proxmox-ve: 5.3-1 (running kernel: 4.15.18-1-pve)
pve-manager: 5.3-9 (running version: 5.3-9/ba817b29)

Any ideas?

Check the switch configs and your bond mode (with 'ip -details a')
