Are people on this mailing list seeing increased CPU usage when using 
MariaDB 10.6.11 with PowerDNS 4.5.4?


I use PowerDNS with the gmysql backend. Last Wednesday, I upgraded 
MariaDB 10.6.10 to 10.6.11 on 8 machines running PowerDNS. Since then, 
MySQL's average CPU usage has increased from 2,5% to 55%. This happens 
on all upgraded machines. However, this issue does not occur on machines 
running MariaDB 10.6.11 without PowerDNS. PowerDNS itself was not 

I am aware that this issue is (most likely) not caused by PowerDNS. I am 
therefore only wondering whether others have seen the same behaviour. If 
so, that would save me some debugging time.

Thank you,

William Edwards
