Disable SELinux, when you use zabbix
When I used Fedora 14 as server before, I found it occurred the below measages
fclose() expects parameter 1 to be resource, boolean given [api/classes/class.cscript.php:626]
Error Description: Permission denied

After I set SELinux, the problem was solved
# setsebool -P httpd_can_network_connect 1
But on Fedora 16, it didn’t work, so I did “setenforce=0″ temporarily.
