VM Network not working normal

[elvinmammadov]

Hello,

We have a strange network problem. Proxmox uses bond (vmbr0) interface . VM also uses vmbr0 interface. We often loose connection to a VM. When I ping the VM ip address from workstations, ping drops too much, but if I ping Proxmox ip address, it goes smooth. Just in case I pinged VM ip address from Proxmox itself, ping also drops there. Proxmox has 64 GB Ram, VM uses 12GB Ram. I run "dmesg" command and it shows me the following warning. Could you please help me to solve this problem?

vmbr0: received packet on bond0 with own address as source address (addr:4c:d9:8f:40:e6:92, vlan:0)
