I encounter a strange deadlock on FreeBSD avoriaz.restart.bel 11.0-RELEASE-p3 FreeBSD 11.0-RELEASE-p3 #0 r308260: Fri Nov 4 02:51:33 CET 2016 root@avoriaz.restart.bel:/usr/obj/usr/src/sys/AVORIAZ amd64 This system is exclusively running on zfs. After 3 or 4 days, `periodic daily` is locked in the directory /usr/local/news/bin [root@avoriaz ~]# ps xa|grep find 85656 - D 0:01.13 find / ( ! -fstype local -o -fstype rdonly ) -prune -o ( -name [#,]* -o -name .#* -o -name a.out -o -nam 462 1 S+ 0:00.00 grep find [root@avoriaz ~]# procstat -f 85656 PID COMM FD T V FLAGS REF OFFSET PRO NAME 85656 find text v r r------- - - - /usr/bin/find 85656 find cwd v d r------- - - - /usr/local/news/bin 85656 find root v d r------- - - - / 85656 find 0 v c r------- 3 0 - /dev/null 85656 find 1 p - rw------ 1 0 - - 85656 find 2 v r -w------ 7 17 - - 85656 find 3 v d r------- 1 0 - /home/root 85656 find 4 v d r------- 1 0 - /home/root 85656 find 5 v d r----n-- 1 533545184 - /usr/local/news/bin [root@avoriaz ~]# If I try `ls /usr/local/news/bin` it is also locked. After `shutdown -r now` the system remain locked after the line '0 0 0 0 0 0' After a reset and reboot I can access /usr/local/news/bin. I delete this directory and reinstall the package `portupgrade -fu news/inn` 5 days later `periodic daily`is locked on the same directory :-o Any idea? Henri
