I thought = it's HardenedBSD-related, but today I also reproduced it on vanilla version of FreeBSD. The issue happens when I build software using my "Sofin" script (which is j= ust plain sh script using sed, awk and other base system utilities to automate software build process). From htop, the issue looks like this: http://s.verknowsys.com/122c70f4414e3ccd903d34746d8284e8.png In this case, two processes turn zombie, and build is stuck (here perl build process hanged on invoking some sed and zsh). This is how build looks from my script side: http://s.verknowsys.com/9fe4981b309b381785e0b4c4ab7d0aea.png (this way I kn= ow it's perl in this case, but I had same issues building Qemu and other softw= are bundles before) It's a very, very severe bug, (would say critical blocker) which is not that hard to reproduce. --=20 You are receiving this mail because: You are the assignee for the bug.=
