From Ana Aman's Blogspot blog today, there's a quick post with a helpful hint for anyone working with PHPMyAdmin experiencing freeze-ups.
If you are using phpmyadmin on a database with more 1500 or more tables, you may experience problems. The page will not load at all so you will not be able to operate propery with phpmyadmin.
Of course you can still run commands from a terminal or console but it is not as confortable as using phpmyadmin.
The solution? Following a bit of digging, Ana discovered that upping the memory limit for the server PHPMyAdmin installed on makes a world of difference.
