https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D263062 t@ida2.de changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |t@ida2.de --- Comment #13 from t@ida2.de --- Hi, I've got a related issue: * Hetzner VM with AMD CPU * FreeBSD 13.2-RELEASE-p2 GENERIC amd64 I've set up a mailrelay which uses rspamd for filtering. rspamd heavily uses DNS queries, therefore unbound is installed and running. 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.=
