https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D281266 --- Comment #5 from regbin <regbinkk+freebsdbugs@gmail.com> --- Tested with both nsd 4.9.1 and 4.10.1. nsd-checkconf returns no errors in both versions. nsd-checkzone returns no error in version 4.9.1, however the same zone files (also the example.com z= one) in version 4.10.1 result in # nsd-checkzone example.com zones/example.com.zone=20 Illegal instruction (core dumped) Starting the service (version 4.10.1) with 'verbosity: 3' produces only: [2024-09-12 15:58:57.130] nsd[12883]: notice: nsd starting (NSD 4.10.1) [2024-09-12 15:58:57.130] nsd[12883]: notice: listen on ip-address ::1@5353 (udp) with server(s): * [2024-09-12 15:58:57.130] nsd[12883]: notice: listen on ip-address ::1@5353 (tcp) with server(s): * which doesn't seem very helpful (already tried with all documented verbosity levels before, hence my comment about no meaningful debugging feedback from= the service). Manually killing the nsd sub-process (since it's not responding to any commands) produces: [2024-09-12 15:59:59.312] nsd[12919]: error: did not get start signal from = main That's how nsd looks like in the process list: nsd 65678 0.0 0.1 68964 8264 - IsJ 16:15 0:00.04 nsd: xfrd (ns= d) nsd 65765 100.0 0.3 50168 37384 - RJ 16:15 0:32.13 - nsd: main (= nsd) I cannot reproduce the problem with the same configuration files on any oth= er machine either. Is it possible that I've hit some zone-parsing simdzone bug= in combination with old hardware? The problematic nsd instance is running on a rather old machine: CPU: Intel(R) Core(TM) i5 CPU 760 @ 2.80GHz (2809.95-MHz K8-class = CPU) SSE4.2 instructions seem to be available, AVX2 on the other hand - not. I'm= not aware of the internal nsd/simdzone workings in such a situation and if that could be the root of the problem at all. --=20 You are receiving this mail because: You are the assignee for the bug.=
