PowerDNS Authoritative Server 4.8.3 STL Exception while serving a connection in main webserver thread: getrandom

Hi,

the fallback to /dev/random does not work like expected as a result the integrated webserver does not work.
every time a request is made the following log gets generated:

STL Exception while serving a connection in main webserver thread: getrandom

logs:

getrandom() failed: Function not implemented, falling back to /dev/urandom

I suspect the libc used in that docker image (which is not from us, to be clear) is too new for your kernel. I'm moving this to Discussions as it does not immediately look like a PowerDNS bug.
