As I understand it in FastCGI mode a php process will launch a number of children equal to the value of the PHP_FCGI_CHILDREN environment variable, I believe that this is the spawning process referred to in the eAccelerator docs, meaning that the shared memory segment would be shared by those PHP_FCGI_CHILDREN processes. But mod_fcgid (unlike mod_fastcgi) assumes that each process it starts directly can only handle a single concurrent request so PHP_FCGI_CHILDREN should be set to 0, meaning that no children will be launched and the shared memory segment will only be used by a single php process. -- Travers Carter - Noggin - http://www.noggin.com.au/ ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
