Lockup: Kernel error netmap_transmit full hwcur 411 hwtail 411 qlen 1023

[Tenn-it]

Last week, my OPensense VM locked up tight as a drum. When I looked at the VM, errros similar to below were flying by:

2025-06-07T09:55:48-04:00   Notice   kernel   548.746013 [4335] netmap_transmit em1 full hwcur 411 hwtail 411 qlen 1023   
2025-06-07T09:55:48-04:00   Notice   kernel   547.903036 [4335] netmap_transmit em1 full hwcur 411 hwtail 411 qlen 1023   
2025-06-07T09:55:47-04:00   Notice   kernel   547.324230 [4335] netmap_transmit xem1 full hwcur 411 hwtail 411 qlen 1023

I rebooted the VM and all was well.

Yesterday it happened again.
I run Zenarmor on the LAN and Suricata on the WAN.


Ive been using this same VM for almost a year and it has always worked great.

This info is on the dashboard


Versions
OPNsense 25.1.7_4-amd64
FreeBSD 14.2-RELEASE-p3
OpenSSL 3.0.16


Memory = 36.25%
Disk = 14%
Firewall states = 0.20%

Any ideas?

Thanks!
