I just realized this today... When I click on the "Settings" links within the admin site and receive a "500 Internal Server Error" page. Viewing the server's error_log reveals the following:
*** glibc detected *** /usr/bin/php-cgi: double free or corruption (!prev): 0x00000000011f5230 ***
[Wed Dec 22 21:35:08 2010] [error] mod_fcgid: process /var/www/cgi-bin/cgi_wrapper/cgi_wrapper(23800) exit(communication error), get unexpected signal 6
I honestly have no idea what it could be, as it doesn't happen in any of the pages where real processing occurs. Plus, I have nothing but green check boxes in the diagnostic pages. Any help is appreciated!
Thank you!
