Hi I was working on my first install of C5 and all was going well, then I got an Internal Server Error, can anyone advise as to why I may have gotten this?

Log is as follows

[Mon Mar 15 16:26:07 2010] [error] [client ***] zend_mm_heap corrupted, referer:http://concrete/index.php?cID=82&mode=edit...

Thanks in advance.
