Yep ;( I understand enterprise and deadline pretty well, I have the same on my side. About 5 second timeout enforced, it could by itself introduce issues and I hope it will be configurable very soon.
Sadly all problems with SSH slaves bring us, CI team, in a very unconfortable situation with our Dev Teams. And it create bad signals about whole CI stability. Did there is a way to activate logging somewhere so we could get better idea of what went wrong ?
