To debug why your code is requesting this kind of memory you can try
following steps.

1. First increase the memory in your ini for you can get rid of this memory
allocation error, you can try to increase this to around 1 GB or something
similar (depends how much memory you have on your machine)... If even
increasing memory upto that HUGE level does not help you, then something is
really really WRONG with your setup, which need to be looked upon within
code for some loops or something like that.

2. If you are able to run your application by increasing Memory, please
install APD on your server. see http://in.php.net/apd
Use APD to track which functions are taking more memory to debug your

Also check if problem is  new on this server and application runs fine or
other machine with different version of PHP, in some recent versions of PHP
few functions behavior has been changed due to which few scripts or older
module behave in unexpected way..

Thanks and Regards
