PHP and mod_fcgid: ap_pass_brigade failed in handle_request_ipc function

This has been asked and answered before https://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

[Thu Nov 19 18:16:48.197238 2015] [fcgid:warn] [pid 6468:tid 139726677858048]
(32)Broken pipe: [client X.X.X.X:41098] mod_fcgid: ap_pass_brigade failed in handle_request_ipc function

The warning has nothing to do with any of the Fcgidxxx options and is simply caused by client's closing their side of the connection before the server gets a chance to respond.

From the actual source:

/* Now pass any remaining response body data to output filters */
if ((rv = ap_pass_brigade(r->output_filters, brigade_stdout)) != APR_SUCCESS) {
    if (!APR_STATUS_IS_ECONNABORTED(rv)) {
        ap_log_rerror(APLOG_MARK, APLOG_WARNING, rv, r,
                      "mod_fcgid: ap_pass_brigade failed in "
                      "handle_request_ipc function");
    }

    return HTTP_INTERNAL_SERVER_ERROR;
}
