Hi,
got the same issue with backport on debian10 1.13.1-1~bpo10+1
We made a fleet of cache servers running Unbound behind a L4 load-balancer.
We got crashes on 3 of the machines all with the same diagnosis.
Here is what we got in dmesg

"Interestingly" it does not happen all the time, as you can see we had a
burst during last week-end, but right now all is calm.
We just restart the service when crash happens for the moment.
