openssh unix dev - Aug 2015 - sftp and ControlPath

Hi guys,

I've check that when using sftp with -o ControlPath=... the first attempt 
just hangs. Can someone point me to appropriate lines in code where can I 
check whats going on?

Maybe it's known issue? I'm using  5.3p1.

cheers,
marcin

Please post a debug log "sftp -vvv ..." - it's essential to figure
out
what is going wrong.

That's pretty old and there have been multiplexing-related bugs fixed since
then.
