ssh and sftp-server work well except when entering quit from client
side for sftp session, Causes session to hang, Ctrl-C closes session
but this must be done using batch from mainframe.
ssh session exiting works fine.

Server - HP NonStop Itanium Blade (TANDEM)
OS - Guardian - J06.09.01
ssh version - openssh-3.7.1p2 (ITUGLIB) running on Floss.

Searched for various Patches, Implemented but not Suscessfull.
