"serve-stale:check prefetch processing of a stale CNAME target" fails on FreeBSD 13
Job #3435305 failed for ff3d25a4 (v9.18).
On FreeBSD 13.2, the check prefetch processing of a stale CNAME target
check failed twice in the recent days:
2023-06-02 01:09:52 INFO:serve-stale I:serve-stale_tmp_q8yamlle:check prefetch processing of a stale CNAME target (214)
2023-06-02 01:09:55 INFO:serve-stale I:serve-stale_tmp_q8yamlle:failed
This was expected:
target.example. 2 IN A 10.53.0.2
But this was the answer:
target.example. 30 IN A 10.53.0.2
We got a stale answer after client timeout (; EDE: 3 (Stale Answer): (client timeout)
), query time was 1840 msec. Locally, I get 2 msec and a non-stale answer.
I was unable to reproduce the problem locally.
