Im running bind 9.3.2-20 on Fedora core 5 but there are some troubles
when im running rndc:

I ran rndc with recursing options and the named stoped.
# rndc recursing rndc: connection to remote host closed
This may indicate that the remote server is using an older version of
the command protocol, this host is not authorized to connect,
or the key is invalid.

I get this messages logs.

Jul 10 15:49:11 rs20s16 named[2903]: exiting (due to assertion failure)

I had the same problem with bind 9.3.1-10 in fedora cora 4
