<p>Hello Matt,</p>
<blockquote>
<blockquote>
<p>[…] this is the 3.1.2-cznic.1~trixie release, hopefully that’s
enough to pull up the symbols for the positions here):</p>
</blockquote>
</blockquote>
<p>Without the corefile, we know nothing, sadly. The binaries are PIE
and we need to know not only where they were mapped but also where glibc
was mapped, how the stack(s) looked like and much more context.</p>
<p>OTOH, it looks like the corefile may be enough very soon, if our
planned magic actually works. I’ll know hopefully at the end of this
week.</p>
<blockquote>
<blockquote>
<p>At least once the same thing instead failed with</p>
<p>bird[617699]: Assertion ‘e->hook’ failed at lib/event.c:239</p>
</blockquote>
<p>This one I managed to hit again by just blocking BFD with iptables
making it go down.</p>
<blockquote>
<p>And, finally, once only restarting bfd with
<code>restart bfd1</code>: […]</p>
</blockquote>
</blockquote>
<p>With that, We’re now going to thoroughly check the BFD restart
because that’s the most likely suspect.</p>
<p>Thanks for your reports!</p>
