PHP Jquery Ajax call throws net::ERR_EMPTY_RESPONSE

Question

I have the following JavaScript code in the page. When the ajax call is made, I could see that the browser inspect/debugger section throws net::ERR_EMPTY_RESPONSE

Answer 1

I have same problem on my page sometimes. I think this happens because of number of variables or how big they are. I have a page that sends a json of about 250 variables without any problem, but this error occurs in this page while about 1500 variables are to be sent. This problem is new. Every thing even with 3000 variables were without problem, before. This problem occurs for me both in chrome and firefox in recent versions. It's not server side error because I have configured apache to revive 1 million variables of 30 Mb data.
