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 at 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 at 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

/usr/local/news/bin
[root at 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
