Re: crontab jobs not running



I checked /etc/shadow, none of the accounts trying to run cron jobs
are disabled. Also, root's crontab's defined jobs are not running,
so I do not think the problem is an expired account.

Our Oracle environment is running on a cluster of redhat boxes.  Each
node is running Redhat 5, x86_64. We are having a problem with our
crontab tasks.  No job seems to be running.  Even root’s crontab jobs
fail to execute.  When I look at /var/log/cron the following lines are
listed over and over:

    Jul 16 13:01:01 server1 crond[1632]: Bad item passed to pam_*_item()
    Jul 16 13:01:01 server1 crond[1632]: CRON (root) ERROR: failed to
open PAM security session: Success
    Jul 16 13:01:01 server1 crond[1632]: CRON (root) ERROR: cannot
set security context

I can’t seem to isolate this issue.   Some other interesting points
that may be related:

*  SE Linux is disabled
*  No cron.allow file exists.
*  The cron.deny file is empty
*  The installed cron packages are:

    anacron.x86_64                            2.3-45.0.1.el5
    crontabs.noarch                           1.10-8
    vixie-cron.x86_64                         4:4.1-77.el5_4.1

*  The installed pam packages are:

    pam.i386                                  0.99.6.2-6.el5_5.2
     installed
    pam.x86_64                                0.99.6.2-6.el5_5.2
     installed
    pam_ccreds.i386                           3-5

    pam_ccreds.x86_64                         3-5

     installed
    pam_smb.x86_64                            1.1.7-7.2.1
     installed

*  The contents of /etc/pam.d/cron is:
    #
    # The PAM configuration file for the cron daemon
    #
    #

    auth       sufficient pam_env.so
   auth       required   pam_rootok.so
   auth       include    system-auth
   account    required   pam_access.so
   account    include    system-auth
   session    required   pam_loginuid.so
   session    include    system-auth
   /etc/pam.d/crond (END)

*  Around the time cron stopped working the following entries started
appearing in /var/log/secure:
    Jul  6 20:40:01 dbtc01 crond[15916]: pam_env(crond:setcred):
pam_putenv: delete non-existent entry; . $AW_HOME/site/sosite
    Jul  6 20:40:01 dbtc01 crond[15916]: pam_env(crond:setcred):
pam_putenv: delete non-existent entry; . $AW_HOME/site/sosite

Any insight is appreciated!  Thank you for your assistance.
