All of a sudden I get this in my log: [Sat Oct 14 19:54:32 2006] [error] ALERT - canary mismatch on efree() - heap overflow or double efree detected (attacker '192.168.1.4', file '/www/vhosts/asarian-host.net/htdocs/phpMyAdmin/index.php') This is not good. If a simple thing like phpMyAdmin causes it, then I will have to disable the Suhosin-Patch (which propably means recompiling from scratch, right?). Barring such drastic action, does anyone have a clue how to solve this? Or what's causing it even. Thanks, - Mark
