But what does the > signal 11 mean ? Is it EDEADLK in sys/sys/errno.h ? I think signal 11 refers to SIGSEGV (segmentation violation). However, I have no idea why a bunch of processes would do that during shutdown? rick > > If yes, then why they get dead locked ? > > > Best regards, > Zhenlei > >

a very, very long time ago (late '90s) I reported something like that to Jordan Hubbard. He suggested HW issues ... honestly can't remember whether he was right :-/ On Fri, Jul 12, 2024 at 7:03 AM Rick Macklem wrote: > On Thu, Jul 11, 2024 at 8:40 PM Zhenlei Huang wrote: > > > > Hi > > > > I observed something weird on Release 14.1. > > > > When rebooting my dev machine, I got > > > > ---<>--- > > Copyright (c) 1992-2023 The FreeBSD Project. > > Copyright (c) 1979, 1980, 1983, 1986, 1988, 1989, 1991, 1992, 1993, 1994 > > The Regents of the University of California.
