Hi Ondrey and others! I have tested 9.20.4-3+ubuntu24.04.1+deb.sury.org+1 on one of our RcodeZero production nodes for 1 week and have not encountered any timeouts anymore. XFR speed also seems fine now.

Can you test a development branch or do you need fix on top of 9.20? Ondrej -- Ondřej Surý (He/Him) ond...@isc.org<mailto:ond...@isc.org> My working hours and your working hours may be different.

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 fromhttps://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.
