I did this also:

ssh from cron stops here:
-------------------------------------- 8< --------------------------------------
debug2: channel 0: close_read
debug2: channel 0: input open -> drain
debug2: channel 0: ibuf empty
debug2: channel 0: send eof
debug2: channel 0: input drain -> closed
Stopping named.
Waiting for PIDS: 8022.
Starting named.
debug1: client_input_channel_req: channel 0 rtype exit-status reply 0
-------------------------------------- 8< --------------------------------------

ssh from console:
-------------------------------------- 8< --------------------------------------
debug2: channel 0: close_read
debug2: channel 0: input open -> drain
debug2: channel 0: ibuf empty
debug2: channel 0: send eof
debug2: channel 0: input drain -> closed

debug1: Transferred: stdin 0, stdout 0, stderr 27 bytes in 4.0 seconds
debug1: Bytes per second: stdin 0.0, stdout 0.0, stderr 6.7

-------------------------------------- 8< --------------------------------------

The client seems not to receive eof on channel 0.

I also tried to plaster debug("") statements at interesting 
places in sshd/session.c in order to find out, where it gets
stuck, but I didn't succeed in finding out.

Another interesting thing is maybe: The ssh client OpenSSH_3.7p1 on
a solaris 8 machine.
Restarting named on another solaris host this way works.
Where it doesn't work is a NetBSD-1.6 Host (sshd version OpenSSH_3.4 
NetBSD_Secure_Shell-20030916a).
