13.0-RELEASE-p7, AMD Q35, "tcp_inpcb kern.ipc.maxsockets limit reached"

Hi there:

Got 2 VMs running release above in AMD with chipset Q35 (3 x vCPUs and 4GB RAM).

The network load is not significantly high and I'd already adjusted the Maxsockets as per:
kern.ipc.maxsockets: 126734

At the time I'm writing this:
Code: 
vmstat -z | grep inpcb
udp_inpcb:              488, 126734,       0,   13360,   77912,   0,   0,   0
tcp_inpcb:              488, 126734,     122,    9062,   83451,   0,   0,   0
udplite_inpcb:          488, 126734,       0,       0,       0,   0,   0,   0
Quite often, the "tcp_inpcb kern.ipc.maxsockets limit reached" starts to pop up in messages and so far the only workaround is to reboot.

Any help in how to better diagnose / troubleshoot this highly appreciated. It's been very troublesome in our env.

Additional details, please let me know

Thanks!
 
Are you getting this in the VMs? Or the host? What hypervisor is the host running?
 
Hi:
Thanks for your response.
On the VMs.
They've been setup in Hetzner's public cloud (https://www.hetzner.com), where I know they use AMD Q35 but not sure what type of HV.
Just in case this helps, we also set up OPNSense running a BSD-12 kernel and they suggested to move this VM to i440fx instead, since it was known that 12 is not supported in Q35, and all good.
But as far as I know, 13 should be fully supported.
Thx
 
The cloud provider migrated these 2 VMS to their legacy HV, based on i440fx and this got fixed.
Apparently 13.0 still got issues with AMD + Q35.
