strange security message regarding sshd

[dave]

Hello,
    Just checked the security report on one of my machines and i saw this
strange output:

Dec 16 07:36:38 zeus sshd[84399]: error: rexec of /usr/sbin/sshd failed: No
such file or directory
Dec 16 07:53:43 zeus sshd[84484]: error: rexec of /usr/sbin/sshd failed: No
such file or directory
Dec 16 07:55:56 zeus sshd[84484]: fatal: Write failed: Operation not
permitted
Dec 16 07:56:52 zeus sshd[84510]: error: rexec of /usr/sbin/sshd failed: No
such file or directory
Dec 16 21:54:43 zeus sshd[57065]: error: rexec of /usr/sbin/sshd failed: No
such file or directory

This is on a 5.3 box and sshd is in /usr/local/sbin i am not sure why i'd be
seeing this. Any suggestions?
Thanks.
Dave.
