'service crond restart' should help to eliminate this intermittent error.
Comment 2 Johan Cwiklinski 2008-02-20 02:59:09 EST
Indeed, that solves the issue... 

Sorry, I should have tried this.

Some more explanation on why this is impossible to fix would be helpful.  Should
a bug be filed against crond?

Comment 6 Tomas Mraz 2008-02-21 12:31:34 EST
Pam probably could restart crond but it hardly can restart whatever other
daemons which can have loaded pam libraries. So the only possible fix for this
is just to reboot the machine. Or the administrator, who knows all the services
and daemons running on his machine, which loaded PAM library, can restart them.
This cannot be handled in any reasonably reliable and non-hackish way in the pam

Comment 8 Jan ONDREJ 2008-02-21 12:40:19 EST
A solution can be to "do not release" new versions of pam in live of a fedora
distribution. New packages can go into fedora-devel, but not into stable updates.

After each upgrade an user must reboot it's machine to load new kernel and fix
also this problem.

Each update for stable update need to be compatible with older config files and
also binary compatible with applications, which can not be automatically
restarted. An user also can do automatic config update, if it is possible.
