mod_fcgid Warnings

Submitted by paul.kelly on Wed, 01/04/2012 - 03:22

I am getting a lot of these, at the moment-
[Wed Jan 04 08:11:58 2012] [warn] mod_fcgid: process 6073 graceful kill fail, sending SIGKILL

[Wed Jan 04 08:13:50 2012] [warn] mod_fcgid: process 6024 graceful kill fail, sending SIGKILL

[Wed Jan 04 08:16:48 2012] [warn] mod_fcgid: process 6442 graceful kill fail, sending SIGKILL

[Wed Jan 04 08:19:48 2012] [warn] mod_fcgid: process 6441 graceful kill fail, sending SIGKILL

[Wed Jan 04 08:24:45 2012] [warn] mod_fcgid: process 6779 graceful kill fail, sending SIGKILL

[Wed Jan 04 08:25:34 2012] [warn] mod_fcgid: process 6727 graceful kill fail, sending SIGKILL

[Wed Jan 04 08:25:50 2012] [warn] mod_fcgid: process 7191 graceful kill fail, sending SIGKILL

Are there any obvious things to look at to try and resolve?

Status: 
Closed (fixed)

Howdy -- that can sometimes happen with FCGID. It's not always possible to correct it.

But, one thing you could try doing is to set "FcgidErrorScanInterval" in your main Apache config (/etc/httpd/conf/httpd.conf).

Normally, it's set to 3 seconds -- but when killing off FCGID processes, if they're taking longer than 3 seconds to exit, you could try setting it to a higher value.

Details on that setting are here:

Do these happen all the time, or only when the Apache configuration is applied?

It looks like a "graceful" Apache config update is being done, but the PHP processes aren't exiting quickly enough for Apache and thus it is killing them. This is pretty harmless though ..
