Hi,
It seems that it is memory limit issue. You might want to try increasing your memory limit for that particular page. First find out the peak memory usage for that page:
echo memory_get_peak_usage(true);
Then set your memory limit appropriately:
ini_set("memory_limit","1024M");
Or edit the php.ini file:
max_execution_time = 1600; Maximum execution time of each script, in seconds
max_input_time = 1600 ; Maximum amount of time each script may spend parsing request data
memory_limit = 80M ; Maximum amount of memory a script may consume (8MB)
And please refer the helpful information:

Hope it can help you.
