Greetings y'all. I searched back to June in this forum area and couldn't find any related posts, so here goes my issue:

I can no longer start the Zenarmor packet engine and I get these errors in notifications area:

* Error parsing lan interface configuration, bailing out

* Failed initializing network interfaces
netmap_register_if: igc2: NIOCREGIF ioctl failed for the interface: Cannot allocate memory

This issue started occurring after I set the following tunables on my Opnsense firewall:

dev.netmap.buf_num : 1000000
dev.netmap.ring_size : 4096
dev.netmap.generic_ringsize : 4096
dev.igc.0.fc : 0
dev.igc.1.fc : 0
dev.igc.2.fc : 0
hw.igc.max_interrupt_rate : 12000


My firewall was also restarted after making the above changes as well.

Current version and mode:
OPNsense 25.7.7_4-amd64
FreeBSD 14.3-RELEASE-p4
Zenarmor netmap is in emulated mode
