Sure. And if you decrease the probability to zero, you don't have a problem any more. > What about Radek Podgorny - I think he doesn't use cron to > start runsvdir, and he has issue with ssh..? I don't know the details of his problem. > And what does mean 'I continue to doubt' - you think we're lying to you?! 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.
