Please see https://wiki.fd.io/view/VPP/BugReports. Just to confirm: you’re
using LISP-GPE, right? Please send vpp version and configuration info.
Anyhow, the clib_warning “vnet[18358]: next_index_to_iface:101: next_index not
associated to an interface!” suggests that an immediate NULL pointer crash will
follow, with PR = { 1.0 }.
Note “faulting address 0x8,” which confirms that thought.
I’ll ping the right person.
Thanks... Dave

Subject: [vpp-dev] VPP crash after days of heavy traffic, next_index is not
associated to an interface #vpp_stability
Hello,
I've encountered a crash I've not seen posted anywhere.
We have a test setup running NAT and on average around 5 Gbps/500 kpps of
traffic. After 24-48 hours, VPP crashes with the following error:
vnet[18358]: next_index_to_iface:101: next_index not associated to an interface!
vnet[18358]: received signal SIGSEGV, PC 0x7faf14fe8608, faulting address 0x8

This has now occurred twice over the last four days.
Any ideas? Any other information that I can provide? I believe I've seen
somewhere that VPP can do a full crash dump (or perhaps just core?) but I
haven't seen the location of it.
Thanks,
John
