But the PF_RING balancing is done in the kernel, I think? As I said
before, I like having "whole" suri instances tied to a CPU.

Do you use cluster_flow or cluster_round_robin? What do you have as
set_cpu_affinity and detect_thread_ratio?

Still not got to the bottom of killing suricata leading to core dumps,
both with yesterday's git version and today's (and with runmode=autofp
and runmode=single).

Of course, some of the rules have changed a bit (my custom anti-phishing
ones built from the APER project phishing_links list), but no more than
usual! Time to try disabling them I suppose ...

Best Wishes,
Chris
