[Pdns-users] CPU Usage Regression in Recursor 4.9.1?

[Christoph]

Hi Winfried,

thanks for your email.

we can rule that out because the recursor uptime graph has no resets
and we have prometheus alert rules that tell us about recursor restarts.
We have put that in place after the crashes related to [1] which we did 
not detect in time back then.
