Sure. And if you decrease the probability to zero, you don't have a 
problem any more.

I don't know the details of his problem.

No, I just haven't seen any evidence. I suspect you are misinterpreting 
the misbehaviour of some program started from ssh, and attributing that 
program's failures to ssh. ssh is always used to start other programs, and 
other programs can always generate zombies. There's nothing ssh can do to 
prevent a child program of it from creating zombies. If ssh is at fault, 
details would be useful, because then someone can find the fault in ssh 
and fix it. Until someone provides evidence that ssh is creating zombies, 
then it's quite reasonable for me to assume that it isn't doing so.

I remain convinced that your problem can be fixed by using runsvdir and 
runsv as they are designed to be used. We can advise you how to do that. 
But if you'd prefer to do strange things with cron, and continue to have 
problems, and point fingers at runit/glibc/kernel, then you have a free 
choice to do that.
