sftp localhost exits after authentication?

[hari sekar]

Hi,
  I use openssh-2.9p2 on a LynxOS i386 system. The ssh
and scp clients work fine. Even sftp from other Linux
systems works. But, if I make sftp to the localhost
(LynxOS), the authentication succeeds, prints sftp>
prompt and then exits. I don't know why this happens.
I have not set the euid of ssh program to root as it
does not work in LynxOS (may be problem with saved
ids). Might this be a problem. I have attached the
debug output of the client program. 
Can I expect some help,
Hari.
