Unbound at 100% CPU and restart in loop since 23.7.3

[Unonyme]

Hello, I'm a little bit blocked with opnsense since i've upgraded to 23.7.3
I've check with a command :

Code Select Expand

ps -aux | grep unb
It seems to crash in less than 30 seconds :-\

Code Select Expand

unbound 59002   0.0  0.3  84904  43452  -  Ss   10:18      0:00.22 /usr/local/sbin/unbound -c /var/unbound/unbound.conf

I tried some tweaks as I read many issues with unbound here  :-\
(besides, I'm surprised by the recurring instability of unbound, it's not the first time i'm in trouble)

- disable suricata (it was eating CPU in coordination with unbound)
- disable DNS blocking lists
- disable Unbound DNS reporting
- disable DHCP leases registering

I tried to disable unboundDNS and activate DNSmasq (first time i try) but it seems it has the same behaviour, DNSmasq restart in  loop  :(

Have you any advice ?

Could you give more details about "100% CPU".
What is reported by "top" command?

Well, it's not totally 100% now i disable many things,
but every restart, i can see that cpu peak on load

The main issue is that while it's crashing, request to DNS can timeout or take more than 5 sec  :-[
