One of my pdns name servers has suddenly stopped resolving, giving a

Quite possibly because it's not running powerdns at all, it's running
bind 9 - or at least claims to be.
$ dig +short @ns6.convergent-ict.com version.bind txt chaos
"9.16.1-Ubuntu"
$ dig +short @ns7.convergent-ict.com version.bind txt chaos
"PowerDNS Authoritative Server 4.2.1"
Maybe what has happened is that someone has installed/started bind on
that server, it bound to port 53, and this in turn is stopping powerdns
from starting.
BTW, this makes it very clear why the "out in the open" support policy
is so important! :-)
Also, do note that powerdns 4.2 is due to go end-of-life soon:
