https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D272775 Bug ID: 272775 Summary: procfs "file" entry pointing to nothing? Product: Base System Version: 13.2-RELEASE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: pen@lysator.liu.se I just noticed that one entry of /proc/<pid>/file which usually looks like a symlink pointing to the real path of the process didn't point to anything? # ps auxww|egrep win root 3236 0.0 0.0 97940 104424 - Ss 22:22 0:02.58 /liu/sbin/winbindd --daemon --configfile=3D/liu/etc/samba/smb.conf ... # cat /var/samba/run/winbindd.pid=20 3236 # ls /proc/3236/ cmdline etype fpregs mem notepg regs status dbregs file map note osrel rlimit # /proc/3236/file -V /proc/3236/file: Command not found. # ls -l /proc/3236 total 0 -r--r--r-- 1 root wheel 0 Jul 28 15:00 cmdline -rw------- 1 root wheel 0 Jul 28 15:00 dbregs -r--r--r-- 1 root wheel 0 Jul 28 15:00 etype ls: /proc/3236/file: No such file or directory lr--r--r-- 1 root wheel 0 Jul 28 15:00 file -rw------- 1 root wheel 0 Jul 28 15:00 fpregs -r--r--r-- 1 root wheel 0 Jul 28 15:00 map -rw------- 1 root wheel 0 Jul 28 15:00 mem --w------- 1 root wheel 0 Jul 28 15:00 note --w------- 1 root wheel 0 Jul 28 15:00 notepg -rw------- 1 root wheel 0 Jul 28 15:00 osrel -rw------- 1 root wheel 0 Jul 28 15:00 regs -r--r--r-- 1 root wheel 0 Jul 28 15:00 rlimit -r--r--r-- 1 root wheel 0 Jul 28 15:00 status Of all the processes listed in /proc, this was the only one displaying this behavious. When I restarted winbindd the problem went away. Is this the same/similar problem as with the fdescfs filesystem we've discu= ssed in issue 272127 regarding filesystem vnode cache? --=20 You are receiving this mail because: You are the assignee for the bug.=
