I‘ve created a file as follows:
ls -l -Z /etc/cron.d/vnstat
-rw-r–r–. root root system_u:object_r:system_cron_spool_t:s0 /etc/cron.d/vnstat
I’ve created a new file /etc/cron.d/vnstat.custom.interface:
ls -l -Z /etc/cron.d/vnstat.custom.interface
-rw-r–r–. root root unconfined_u:object_r:system_cron_spool_t:s0 /etc/cron.d/vnstat.custom.interface
The /etc/cron.d/vnstat is part of default vnstat package. I’ve installed my own version of the same. But, due to SELinux security cron job is not running. How do I change file SELinux security contex under RHEL / CentOS 6 Linux server to system_u:object_r:system_cron_spool_t:s0 from unconfined_u:object_r:system_cron_spool_t:s0 for /etc/cron.d/vnstat.custom.interface file?

I setup a CentOS Linux based Linux server running as a gateway and firewall server. However, I’m getting the following messages in the /var/log/messages log file:
Dec 20 00:41:01 fw01 kernel: Neighbour table overflow.
Dec 20 00:41:01 fw01 last message repeated 20 times
OR
Dec 20 00:41:01 fw03 kernel: [ 8987.821184] Neighbour table overflow.
Dec 20 00:41:01 fw03 kernel: [ 8987.860465] printk: 100 messages suppressed.
Why does kernel throw “Neighbour table overflow” messages in syslog? How do I fix this problem under Debian / CentOS / RHEL / Fedora / Ubuntu Linux?
