Package: openssh-client Version: 1:5.6p1-1 Severity: normal Since switching on ControlPersist, I have dozens of defunct ssh processes in the process table, e.g.: madduck 28025 0.0 0.0 40612 2784 pts/8 S+ 09:17 0:00 ssh pulse madduck 28028 0.0 0.0 0 0 pts/8 Z+ 09:17 0:00 [ssh] <defunct> madduck 28029 0.0 0.0 40704 1188 ? Ss 09:17 0:00 ssh pulse The PIDs suggest thatt hese are related. It looks to me that the second process is the clone process, which, according to strace, only does: open("/dev/null", O_RDWR) = 5 dup2(5, 0) = 0 dup2(5, 1) = 1 close(5) = 0 clone(child_stack=0, flags=CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID|SIGCHLD, child_tidptr=0x7f901060c9f0) = 20475 exit_group(0) = ? It looks like the parent is not reaping this clone after it terminates. -- System Information: Debian Release: squeeze/sid APT prefers unstable APT policy: (500, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 2.6.35-trunk-amd64 (SMP w/4 CPU cores) Locale: LANG=en_NZ, LC_CTYPE=en_NZ.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages openssh-client depends on: ii adduser 3.112 add and remove users and groups ii debconf [debconf-2.0] 1.5.35 Debian configuration management sy ii dpkg 1.15.8.4 Debian package management system ii libc6 2.11.2-2 Embedded GNU C Library: Shared lib ii libedit2 2.11-20080614-1 BSD editline and history libraries ii libgssapi-krb5-2 1.8.3+dfsg~beta1-1 MIT Kerberos runtime libraries - k ii libssl0.9.8 0.9.8o-1 SSL shared libraries ii passwd 1:4.1.4.2-1 change and administer password and ii zlib1g 1:1.2.3.4.dfsg-3 compression library - runtime Versions of packages openssh-client recommends: ii openssh-blacklist 0.4.1 list of default blacklisted OpenSS ii openssh-blacklist-extra 0.4.1 list of non-default blacklisted Op ii xauth 1:1.0.4-1 X authentication utility Versions of packages openssh-client suggests: ii gtk-led-askpass [ssh-askpass] 0.10-2 GTK+ password dialog suitable for pn keychain <none> (no description available) pn libpam-ssh <none> (no description available) -- Configuration Files: /etc/ssh/ssh_config changed [not included] -- no debconf information -- .''`. martin f. krafft <madduck@d.o> Related projects: : :' : proud Debian developer http://debiansystem.info `. `'` http://people.debian.org/~madduck http://vcs-pkg.org `- Debian - when you have better things to do than fixing systems
