Increase PHP allowed memory size limits

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 842489 bytes) in /var/www/wsf2008/includes/database.mysql.inc on line 380

If you have control of your own host:

ben@server:~$ sudo vi /etc/php5/apache2/php.ini

/Resource Limits plus RETURN to search
i to edit

max_execution_time = 60 ; Maximum execution time of each script, in seconds
max_input_time = 120 ; Maximum amount of time each script may spend parsing request data
memory_limit = 64M ; Maximum amount of memory a script may consume (16MB)

ben@server:~$ sudo /usr/sbin/apache2ctl graceful

Note: In addition to the "Fatal error: allowed memory size" message, on one occasion Agaric received this warning about MySQL tables, presumably a result of PHP hitting its RAM limits.
