As we still have several timeouts I downgraded our server to 9.18. If you know
another workaround or need someone to test new version please let me know.
Thanks

Correcting myself: event with { reuseport no; }; and UV_THREADPOOL_SIZE=12
still timeouts happen, but the situation improved a lot.

Are your running with options { reuseport no; }; ?
You might want to try that.
After setting reuseport no; (and UV_THREADPOOL_SIZE=12) I have not seen any
timeouts anymore.
Anyway, this:
TID 8917:
#0 0x00007b385aa6daa9 cds_lfht_destroy -
/usr/lib/x86_64-linux-gnu/liburcu-cds.so.8.1.0
caught my eye. Are the zones you are hosting particularly large on GLUE?
I don’T know and I have not checked yet. One of the affected zones is .ch. You
could download the zone from https://zonedata.switch.ch/ And they are using
NSEC (not NSEC3 as I have written before)
Also if you have more eu-stack, can you confirm this is the pattern now?
After setting reuseport no; I do not have stack-traces any more. But if that
would help you I can undo the workaround next week to collect traces.
Thanks
Klaus
