Hello,

My PHP installation is configured to accept 8M of post data and use to  
128M  
of physical memory.

I have also configured following in nginx conf

client\_body\_buffer\_size 100k;  
client\_header\_buffer\_size 100k;  
client\_max\_body\_size 16m;  
large\_client\_header\_buffers 200 100k;

When i try to post large data, some data from the last last textboxes is  
truncated  
There are over 200 textboxes on the page.  
And i am getting the data in post only for 185 text boxes.

Thanks in advance.

I would suppose it’s a php configuration problem, see here:
