https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=227285 --- Comment #4 from Jan Kokemüller <jan.kokemueller@gmail.com> --- To uncover the bug it helps to run multiple instances at the same time and to remove the debug output or to pipe it into /dev/null. After a few seconds, at least some instances should be dead. I've tested only amd64 for now. I could reproduce it on stock FreeBSD 10/11 systems: FreeBSD 10.3-RELEASE-p24 FreeBSD 10.3-RELEASE-p24 #0: Wed Nov 15 04:57:40 UTC 2017 root@amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC amd64 hw.model: Intel(R) Celeron(R) CPU N3150 @ 1.60GHz FreeBSD 11.1-RELEASE-p7 FreeBSD 11.1-RELEASE-p7 #0: Tue Mar 6 09:33:30 UTC 2018 root@amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC amd64 hw.model: Intel(R) Celeron(R) CPU G530 @ 2.40GHz -- You are receiving this mail because: You are the assignee for the bug.help
