Description of problem: Hundreds of messages in the logs saying "SELinux is preventing omiagent (initrc_t) "write" to ./status (unconfined_t)"

omiagent is a daemon installed by SCOM 2012 R2 to monitor Linux server health and performance.

I am unable to find the "./status" file to run 'restorecon'.

Version-Release number of selected component (if applicable):

How reproducible: Constant

As the messages suggest, I ran "sealert -l 867d72ac-1ea2-42ff-97ab-821938b68e54"

SELinux is preventing omiagent (initrc_t) "write" to ./status (udev_t).

Detailed Description:

[SELinux is in permissive mode, the operation would have been denied but was
permitted due to permissive mode.]

SELinux denied access requested by omiagent. It is not expected that this access
is required by omiagent and this access may signal an intrusion attempt. It is
also possible that the specific version or configuration of the application is
causing it to require additional access.

Allowing Access:

Sometimes labeling problems can cause SELinux denials. You could try to restore
the default system file context for ./status,

restorecon -v './status'

If this does not work, there is currently no automatic way to allow this access.
Instead, you can generate a local policy module to allow this access - see FAQ
(http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Or you can disable
SELinux protection altogether. Disabling SELinux protection is not recommended.
Please file a bug report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi)
against this package.

You will need to add a local policy to address this issue in RHEL5.
