I‘m running the Mediawiki software under Apache web server running on the Unix operating systems. I’m getting the following in my php error log:
PHP Fatal error: Cannot redeclare wfProfileIn() (previously declared in /var/www/html/wiki/includes/profiler/Profiler.php:14) in /var/www/html/wiki/includes/ProfilerStub.php on line 25.
How do I fix this problem under Mediawiki version 1.18.0?

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?
