Netmap Seg faults

Has anyone experienced segfaults with Bro + Netmap when executing a ‘broctrl stop’?

1487299650.431866 818913 packets received on interface bro}3, 0 dropped
/opt/bro/share/broctl/scripts/run-bro: line 107: 4821 Segmentation fault nohup “$mybro” “$@”


Also seeing these messages in dmesg:

Is this on FreeBSD or on Linux? :slight_smile:

In any case, on FreeBSD I hae not seen segfaults with Bro & Netmap on a
broctl stop; however, some machines of us still like to crash when
starting up Bro in the same configuration. (Crash as in apparently
kernel-crash and reboot).
