Question

Running a MySQL intensive PHP script that is failing. Apache log reports this:

[Wed Jan 13 00:20:10 2010] [error] [client xxx.xx.xxx.xxxx] (70007)
The timeou         


        

Answer 1

There is another timeout value placed not in php itself but in apache server. It will brake script when nothing is on output for specified time so when doing harder work in PHP you can reach this limit. Just echo anything back to browser (not buffers!) or increase apache timeout value to safe value, as far as I remember it's KeepAliveTimeOut apache property. Good luck :)
