    I'm running PHP via fastcgi and getting a 500 error saying "fastcgi process has failed frequently recently". However, no errors are occuring in PHP. The error only occurs when traffic gets higher than usual. Is it possible for something other than PHP to cause this error?

    fastcgi php

    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:


    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.
