Did you check that named was still listeing on port tcp 953? What does
"netstat -Sa|grep rndc" tells you?

Can you telnet localhost 953?

Did you check that rndc and named are of the same version? Calling
rndc with no argument should give you the version, and any dig request
should give you the version of named. Do they have the same
installation date?
