sshd fails to run

Hi,

When I try to start sshd I get the following error and then sshd stops running

I am running the following configuration

OS=AIX 5200-09-01
OpenSSH_3.7.1p2, SSH protocols 1.5/2.0
OpenSSL 0.9.6g 
zlib 1.1.4

There are host keys available for protocols 1 & 2

Any help would be appreciated.
Thanks in advance,
