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

pam_krb5.i386 2.2.14-18.el5

pam_krb5.x86_64 2.2.14-18.el5

pam_passwdqc.i386 1.0.2-1.2.2

pam_smb.i386 1.1.7-7.2.1
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.
