Selinux file_contexts: Multiple same specifications for /usr/local/lost\+found.

If you receive the message “/etc/selinux/targeted/contexts/files/file_contexts: Multiple same specifications for /usr/local/lost\+found.” in your email, this usually means the system thinks you have a user account home directory in /usr/local and this user is allowed to ssh to your server.

If there is a system account, make sure you change the shell to /sbin/nologin or /bin/false. In order for the changes to take effect, run

semodule -B

PHP Fatal error: Allowed memory size of xxxxx bytes exhausted

Posted by Jason Web Hosting Wednesday 8 April 2009 2:06 pm

You may see the error message “PHP Fatal error:  Allowed memory size of xxxxx bytes exhausted (tried to allocate xxxxxxx bytes) in Unknown on line 0″ while accessing some php pages which indicates that those php files requires more memory for it to execute than the one specified in php.ini file. If the memory_limit value is manipulated in server side php.ini file, it will be applied to all the php files server side.

In order to overcome the error without modifying the server side php.ini file, you need to use the ini_set function to increase the memory limit inserting the following code in the php file itself. Keep on increasing the memory limit unless the error disappears.

ini_set(”memory_limit”,”64M”);
