Description of problem:
its fresh installation of rhel7 from 20131115.
After few hours of running it just happened without any specific user action.
SELinux is preventing /usr/sbin/rsyslogd from 'open' accesses on the chr_file /dev/pts/0.

*****  Plugin catchall_boolean (47.5 confidence) suggests   ******************

If you want to allow logging to syslogd use tty
Then you must tell SELinux about this by enabling the 'logging_syslogd_use_tty' boolean.
You can read 'None' man page for more details.
Do
setsebool -P logging_syslogd_use_tty 1

*****  Plugin catchall_boolean (47.5 confidence) suggests   ******************

If you want to allow daemons to use tty
Then you must tell SELinux about this by enabling the 'daemons_use_tty' boolean.
You can read 'None' man page for more details.
Do
setsebool -P daemons_use_tty 1

*****  Plugin catchall (6.38 confidence) suggests   **************************

If you believe that rsyslogd should be allowed open access on the 0 chr_file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep 72733A6D61696E20513A526567 /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
