rndc status command hangs in bind 9.14.2

[Andi Vajda]

  Hi,

I've been running bind 9.12 on netbsd 7.2 without any issues.
The bind-9.12 package is now marked deprecated (eol) and we're encouraged to 
upgrade to bind 9.14.

I've been giving it a few tries and, while my server seems to be working 
normally with bind 9.14.2, it doesn't respond to rndc commands.

Running rndc -V status shows rndc stopping after 'send message'.
I see nothing in the logs that would explain this. In particular, my rndc 
key setup is working fine.
I also tried increasing log levels and never got anything added to the logs 
that was triggered by my calling rndc status.

I'm using the exact same configs between 9.12 and 9.14. With a 9.12 server 
rndc works fine (compiled from either version of bind). With a 9.14 server
rndc just hangs after sending its request message to the server. It never 
receives and parses a response. If I ctrl-c it, it says that "recv" got 
interrupted.

Is there something different about 9.14 defaults that I now need to include 
in my config to get past this ?
My named is running in a chroot cage.

Thank you for your assistance and clues !
