It's been left 40+ days since then. Very little usage - but I have over 120 'stuck' sshd daemons. I initially posted to the freebsd-xen list (this box is running under Xen) as we've a number of other FBSD10 boxes that don't have the issue (but these get more usage, and frequent restarts). It now looks like it's not a Xen issue - but a FBSD10 issue... I've left the machine 'as-is' with all these zombies / stuck sshd's - if anyone wants me to run anything against / on it? I can't see that this has been fixed in a newer -stable? Cheers, -Karl
