Hello everyone,
I had few unexpected crashes with my VPP router (I use LCP).
Everytime logs look something like this:
1. VPP Unit

> 0x756823d2a072

2. Kernel log
[Usual systemd init startup sequence log (services starting one by one)]

I use Intel X710 as my main NIC under 08.00 pcie address.
Dataplane crashes then it restarts, but today it got into bootloop with
following message:
>
> Apr 23 06:52:32 gw vpp[422096]: vpp[422096]: vlib_stats_init: stat segment
> mmap failure
> Apr 23 06:52:32 gw vpp[422096]: vlib_stats_init: stat segment mmap failure

This time vfio-pci section was missing from kernel log and I had to reboot the
machine to make VPP start again.
Configuration for my stats segment looks like this:
>

vppctl show memory stats-segment

VPP ( vpp v25.10-release built by root on a55774381098 at 2025-10-29T10:59:07)
is installed straight from deb repo on vanilla Ubuntu 24.04 LTS non HWE.
Can anyone point me towards how to debug this? It looks like VPP is running out
of memory, but hugepages and memory seems plentiful.
Best regards,
Łukasz Jarosz
