Arch Linux

Description:
Some time after startup (usually 1-3 days), monerod starts to consume a high amount of CPU time on two threads (each thread 80+% of a Ryzen 5950X CPU thread).
To at least get any info on what is causing it I built the package myself with debug symbols enabled by adding the options !strip and debug to the PKGBUILD and changing CMAKE_BUILD_TYPE from release to debug.
Output of perf top -a and htop: https://gist.github.com/jkhsjdhjs/03a1f5a8c7198de2463ca7c9068898bd

Since the perf top output contains some SSL related stuff I thought that it might be related to this package being linked against OpenSSL 3, while the official binaries are linked against OpenSSL 1.1. Thus I built monerod with OpenSSL 1.1 myself by exporting PKG_CONFIG_PATH=/usr/lib/openssl-1.1/pkgconfig in the build() function of the PKGBUILD.
But the same issue appeared: https://gist.github.com/jkhsjdhjs/4f46c15961f8163f41405696539682db
This package is also linked against unbound, which is currently built with OpenSSL 3, so in the second build monerod was linked against OpenSSL 3 and OpenSSL 1.1. I'm not sure if I'd also have to rebuild unbound with OpenSSL 1.1 to make sure it's not a compatibility issue with OpenSSL 3.

The log file doesn't indicate anything useful. My config is available here: https://gist.github.com/jkhsjdhjs/d6d14560f9e697ed595749946cd49dbc

I haven't been able to reproduce this issue with the official binary (yet, maybe I didn't wait long enough in the last attempt). I'm currently trying to do exactly that again.
