Re: ssh going zombie

on the server kill the ssh server then restart it with the -d flag to put 
it into debug mode.  This process will not fork and will write all debug 
output to the stderr (the window you started it from), then connect with 
winscp and try to duplicate the error you reported. 

it should give you some clues as to what is happening.

    Using sshd under Debian Unstable Openssh  0.9.7e

    When winscp disconnects from our server the scp process goes zombie 
and the ssh process hogs the processor on the server.  This only seams 
to happern with winscp  and not with  scp or  ssh  under  linux. If the 
subprocess is removed from the sshd config file the a sub sshd process 
goes zombie instead and the calling sshd process hogs the processor.

    I'm think it may have somthing to do with the way winscp talks to 
sshd , but the winscp people seam to think this is a problem with sshd. 
I get this feeling this is going to be a problem nobody has a clue on 
and wishes to blame the other party.
