[PVE-User] networking problem inside CT vmbr0: received packet on bond0 with own address as source address

hi friends
we have 2 proxmox nodes here
mox and mox11
in simple cluster after upgrade to the same latest version 5.3-9
BUT
example with chronology
19:05-19:08 reboot lasts about 4 minutes
   node is in round robin state after boot and CTs are not pingable and 
DHCP clients inside CTs are unable to get IP eventhough the DHCP server 
is offering it
19:24 after manual restart networking.service at node level it switch to 
802.3ad and CTs grab their DHCP IP and all appears to be ok
   but after several minutes services inside CTs lost connectivity :-(((
   and weird info "vmbr0: received packet on bond0 with own address as 
source address" INSIDE syslogs of the CTs
PLS what is wrong at network config ?

MANY thanks for any comments
Nada

========== interfaces

but something is wrong with mox11 networking conf
PLS ignore isolated vmbr30,vmbr40 and vmbr50
LXC CTs are just at vmbr0 which was configured to use bond mode 802.3ad
the LAG at switch and network cables were NOT changed for about 1.5year
