Hi
"xfrd: failed reading tcp Operation now in progress" has recently started
cropping up in my logs on an NSD secondary (pulling from a PowerDNS primary).
My other secondary runs Knot and has no issues.
What does the obscure message mean and (more importantly) how do I fix it ? A
reboot of the host did not help and there are no updates pending.
This is Debian Bookworm and NSD is from the distro.
NSD version 4.6.1
