For now the server already has stopped working three times with: Aug 10 07:25:38 mailrelay kernel: [zone: udp_inpcb] kern.ipc.maxsockets lim= it reached I guess the DNS queries are the reason for this. I've just rescaled the VM to Intel, but still it's Q35 chipset: # dmidecode -s baseboard-product-name Standard PC (Q35 + ICH9, 2009) vmstat after the reboot says this: # vmstat -z | egrep 'ITEM|inpcb' ITEM SIZE LIMIT USED FREE REQ FAILSLEEP XDOMAIN udp_inpcb: 496, 256000, 58, 12646, 5519436, 0, 0, = 0 tcp_inpcb: 496, 256000, 47, 465, 1146, 0, 0, = 0 udplite_inpcb: 496, 254671, 0, 0, 0, 0, 0, = 0 If problem persists I'll talk to Hetzner support to change chipset to i440FX and give feedback here. --=20 You are receiving this mail because: You are the assignee for the bug.=
