AIX reboot problem after SSH is installed

[LAM, FELIX]

Hi,

I've installed OpenSSH 3.7.1 on AIX.  After I've installed it, when I
try to reboot the machine using shutdown -Fr command remotely, it
doesn't reboot at all, and it hangs.  If I'm doing it from its terminal
(ie not thru ssh to the remote machine), the machine will reboot.  Do
you know how to fix this problem?  Thanks in advance!

Regards,
Felix
