2012-12-11 10:34:35: (mod_fastcgi.c.1007) if you try do run PHP as FastCGI backend make sure you use the FastCGI enabled version.
You can find out if it is the right one by executing 'php -v' and it should display '(cgi-fcgi)' in the output, NOT (cgi) NOR (cli)

Cannot allocate memory

Looks like lack of resources. Is it VPS or standalone server?
