https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=194995 Bug ID: 194995 Summary: lsof -i panics system Product: Base System Version: 11.0-CURRENT Hardware: amd64 OS: Any Status: Needs Triage Severity: Affects Some People Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: mwlucas@michaelwlucas.com This might be related to https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=194974, but it's a different panic message, so I opened a new PR. I figure the awesome power of bugzilla will let you chain PRs together if needed. Fresh world & kernel, latest official packages: FreeBSD storm 11.0-CURRENT FreeBSD 11.0-CURRENT #7 r274435: Wed Nov 12 11:30:04 EST 2014 mwlucas@storm:/usr/obj/usr/src/sys/GENERIC amd64 ;pkg info lsof lsof-4.88,8 Name : lsof Version : 4.88,8 Installed on : Wed Nov 12 10:27:44 EST 2014 Origin : sysutils/lsof Architecture : freebsd:11:x86:64 Prefix : /usr/local Categories : sysutils Maintainer : ler@lerctr.org WWW : http://people.freebsd.org/~abe/ Comment : Lists information about open files (similar to fstat(1)) Annotations : repo_type : binary repository : FreeBSD Flat size : 223KiB Description : Lsof (LiSt Open Files) lists information about files that are open by the running processes. An open file may be a regular file, a directory, a block special file, a character special file, an executing text reference, a library, a stream or a network file (Internet socket, NFS file or Unix domain socket). See also fstat(1) in the base system. WWW: http://people.freebsd.org/~abe/ Run "lsof -i" and CPU usage starts to climb. In 15-30 seconds I get a panic. I haven't done this for a while, so let me know if I kgdb'd wrong or you want more info. storm/var/crash;kgdb /usr/obj/usr/src/sys/GENERIC/kernel.debug vmcore.0 GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc.
