Greetings,

I am having issues with Suricata allocating host-rings after an upgrade to 25.1.11. This was working before an upgrade of OPNsense from version 25.1.6_4.

I am running RSS.

2025-07-20T04:12:28   Error   suricata   [105418] <Error> -- opening devname netmap:ix1-0/R@conf:host-rings=8 failed: Invalid argument

Thread count                         8            8
Default queue limit                256        10240
Dispatch policy                 hybrid          n/a
Threads bound to CPUs          enabled          n/a
Netstat also properly delays 8 queues.

Anyone have any ideas that aren't turning off RSS? I believe that netmap is going to want a host ring per queue if there are muliple queues, but frankly getting a bit out of my depth here. Any assistance would be appreciated.

Thanks.
