handler for x-httpd-ea-php56 returns invalid result code 70007

hello All,

I am having challenges resolving this persistent 500 internal error that shows up while submitting a POST upload file data of about.

Upon checking the error_log on /usr/local/apache/logs all I see is

handler for application/x-httpd-ea-php56 returned invalid result code 70007

I just need to know exactly what the issue is through a precise error message and not something vague.

It is important to state that I have tweaked php ini config such as:

max_execution_time, max_input_time, memory_limit, post_max_size, upload_max_filesize

But still whenever a file of about 10MB is uploaded, I get the 500 error and log states nothing else except this:

handler for application/x-httpd-ea-php56 returned invalid result code 70007
