<p>Hello Christoph,</p>
<p>I finally managed to reproduce this, and it actually doesn’t have
anything with -R, nor with ASPA directly, but it looks like a bug in
both 3.1.5 and 3.2.0, and the fix will be in upcoming 3.2.1 and
3.1.6.</p>
<p>You may see the WIP branch with all the boring technical details in
our gitlab:
https://gitlab.nic.cz/labs/bird/-/commits/343-bad-journal-release This
link will stop working later but you’ll find the commits by searching
for <code>#343</code> in the commit messages.</p>
<p>I have still several points on my checklist arising from your
reports, thank you so much for them. I’ll get back to you as soon as I
have more progress.</p>
<p>Thank you and have a nice day!</p>
<p>Maria</p>

<p>Hello again,</p>
<p>I managed to get it to crash also on 3.2.0 without the “-R” so, this
might be two instead of just one issue. Without “-R” at least it crashes
only once and not in a loop.</p>
