[Bug 1373] killer freezes thin client sessions
http://bugs.skolelinux.org/show_bug.cgi?id=1373
------- Comment #5 from rgx@gmx.de 2009-09-22 12:01 -------
It turns out that ldap user ids are not resolved by 'ps' and hence killer wants
to kill sh: killer -n gives (among others):
kill(9, 2439) user=11592 command=sh nice=0
Searching in "ps faux", this ** process within sshd session of user "a12-phbeu"
(uid=11592):
root 2433 0.0 0.0 11060 3972 ? Ss 14:43 0:00 \_ sshd:
a12-phbeu [priv]
11592 2435 1.1 0.2 17556 8436 ? R 14:43 0:20 | \_ sshd:

So, please, either
- don't ever kill "sh" processes younger than 1 day,
- or don't kill (seemingly) anonymous processes at all.
