Re: PHP and mod_fcgid: ap_pass_brigade failed in handle_request_ipc function

[Steven Barre <steven@xxxxxxxxxxxxxxxxxxxxxxxx>]

I haven't yet been able to determine a pattern of when it happens. It seems to be all kinds of requests (for PHP pages) that is causing it. We even have a few different CMSs and they are all doing it, so I don't think its a PHP code issue.

What would you recommend I set SendBufferSize to? Its currently not set in my configs and so is the default.

Hi Steven,

from [1] it appears that something goes wrong when flushing data to the output filters chain. Does it happen with a specific set of requests or randomly? 

Shot in the dark: have you also tried to increase the Apache SendBufferSize (https://httpd.apache.org/docs/2.4/mod/mpm_common.html#sendbuffersize)?

OK, so I've been trying to solve this for a while now,. and I still can't even figure out what this error means. Can someone tell me what has gone wrong in fcgi to cause this error?

I posted on Stack Overflow, but haven't gotten much help yet so I'm trying this mailing list. http://stackoverflow.com/questions/33811543/php-and-mod-fcgid-ap-pass-brigade-failed-in-handle-request-ipc-function

========================================

This has been asked and answered before http://stackoverflow.com/a/12686252/219116 but, the solution there is not working for me.

mod_fcgid config

    <IfModule mod_fcgid.c>
      AddHandler    fcgid-script .fcgi
      FcgidIPCDir /var/run/mod_fcgid/
      FcgidProcessTableFile /var/run/mod_fcgid/fcgid_shm

      FcgidIdleTimeout 60
      FcgidProcessLifeTime 120
      FcgidMaxRequestsPerProcess 500
      FcgidMaxProcesses 150
      FcgidMaxProcessesPerClass 144
      FcgidMinProcessesPerClass 0
      FcgidConnectTimeout 30
      FcgidIOTimeout 600
      FcgidIdleScanInterval 10
      FcgidMaxRequestLen 269484032

    </IfModule>

php-cgi script

    #!/bin/bassh
    export PHPRC=/var/www/vhosts/example.com/etc/
    export PHP_FCGI_MAX_REQUESTS=5000
    exec /usr/bin/php-cgi

System details

 - CentOS Linux release 7.1.1503 (Core)
 - httpd-2.4.6-31.el7.centos.x86_64
 - mod_fcgid-2.3.9-4.el7.x86_64
 - php56u-cli-5.6.12-1.ius.centos7.x86_64

So my FcgidMaxRequestsPerProcess is set to 500 and my PHP_FCGI_MAX_REQUESTS is set to 10x that as suggested in the previous answers and the Apache documentation. And yet I still get these errors
