Intensive PHP script failing w/ “The timeout specified has expired” error / ap_content_length_filter

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

I hit a very similar wall as well with Apache 2.4.6 and PHP 5.4.23 FPM/FastCGI.

Symptom:

No matter what I set in PHP or Apache, my script would timeout in 30 seconds and I would see the following in my Apache Error log:

[timestamp] [proxy_fcgi:error] [pid...] (70007)The timeout specified has expired: [client ...] AH01075: Error dispatching request to :

My VirtualHost:

TimeOut  300
KeepAliveTimeout 300


  RequestReadTimeout header=120-240,minrate=500
  RequestReadTimeout body=120,minrate=500



  ProxyTimeout 300



  FcgidConnectTimeout 300

The pesky php script:

ini_set( 'max_execution_time', '120' );
...
ini_restore( 'max_execution_time' );

The Fix: it's a hard coded value in Apache mod_proxy_fcgi

Take a look at the bug report here

• A patch is available (link above)
• The fix doesn't appear to be slated for general release yet (Mar 2014)
