openssh unix dev - Mar 2005 - ssh hang problem under solaris 8

Hi :-)

i have try a hang on exit patch that i found in the web for an old openssh
version, but it dosent help :-(

in a german gdb howto i found a tip that the backtrace output can help to
analyse the problem....

is it a solaris problem ?

Greetings

Frank

What are you doing when it hangs?

Does any of this apply to your situation?

     Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.

i have encountered the same problem. the patch suggested by darren 
tucker did not fix the problem.

thanks,
