[solved] Suricata stopped working after updating to OPNsense 22.7.6

[meschmesch]

After updating to OPNsense 22.7.6 Suricata stopped working. Starting suricata provides 100% CPU and errors:

Code: [Select]

2022-11-02T18:49:11 Error suricata [109401] <Error> -- [ERRCODE: SC_ERR_NETMAP_CREATE(263)] - opening devname netmap:igb0^ failed: Cannot allocate memory
igb0 is WAN. Suricata is running on WAN, Zenarmor is running on LAN and other interfaces (for Zenarmor WAN is not even available for selection).

I have a second machine running with more or less identical configuration (CARP, HA), no problems there.

Thank you!


PS: The problem was Sensei. Previously it was configured to listen on various VLAN and not physical interfaces. It worked fine for 2 years without any complaints. Supposedly an updated made Sensei more picky. After only selecting physical interfaces everything worked fine.
