Until yesterday I presumed without verifying that I have set the php memory limit to 128MB from within drupal in settings.php  in hosting environment as I have done it in my test environment but only when the fatal error msg was displayed I verified the mem limit which was not affected by the changes in the settings.php.

A simple request  to the hosting providers got the memory expanded - php.ini which users don't have access to - So don't frown on the fatal error msg while accessing the modules page after adding the module that you needed.
