Docker: macvlan crashing

Now suddenly I started having an issue which would lock up my box (I'm running +25 containers), the box would run for everything from 15 minutes to 24 hours (sometimes longer) but it would lock up. The only notification I would get would be an exception like this in dmesg: Oct 21 00:51:10 kernel: [22600.504145] ------------[ cut here ]------------ Oct 21 00:51:10 kernel: [22600.504183] WARNING: CPU: 0 PID: 303960 at net/netfilter/nf_conntrack_core.c:1123 __nf_conntrack_confirm+0x3ff/0x480 [nf_conntrack] Oct 21 00:51:10 kernel: [22600.504186] Modules linked in: tcp_diag udp_diag inet_diag xt_nat xt_tcpudp veth macvlan xt_conntrack nft_chain_nat xt_MASQUERADE nf_nat nf_conntrack_netlink nf_conntrack nf_defrag_ipv6 nf_defrag_ipv4 xfrm_user nft_counter xt_addrtype nft_compat nf_tables nfnetlink br_netfilter overlay bridge stp llc mlx5_core(OE) mlxfw(OE) mlxdevm(OE) auxiliary(OE) mlx_compat(OE) p...
