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?

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:
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.
