I am developing script so my members can submit a table of information through an HTML form. This table can sometimes grow to include thousands of input boxes (very large HTML form submission).
These input types are either hidden or text, typically between 1-20 characters per field. When I submit the form with around 1,200 input fields boxes, it goes through fine.
The latest test had just under 4,000 input fields and I got this 503 error upon submission:
Service Temporarily Unavailable
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.
This physical memory size of the post is nowhere near the maximum allowed in a $POST variable (postmax_size = 32M). In addition, I changed my PHPRC file to increase the number of input vars to: max_input_vars = 50000
This still doesn't seem to help and it appears to be an issue with something crashing on the server. Please let me know why this might be happening.
