An example core [0] from CSIT test on VPP debug (+asan) image. So far this issue is only seen in IPsec policy tests (which do not usually use AVF plugin in trending).

The issue reminds me of similar failure (old, logs no longer available) that got fixed by [1] (but my attempt at analogous fix [2] did not help).
