Hi.

I have been wondering this for a while and in my searches in Google there is no direct answer on how to fix this, but my question is the following:

How do I stop error messages like this:

Code:
[Tue Oct 14 01:20:23.963630 2014] [optional_fn_export:error] [pid 10608:tid 140347598362368] AH01871: Optional function test said: GET / HTTP/1.1
[Tue Oct 14 01:20:23.984517 2014] [optional_hook_import:error] [pid 10606:tid 140347682281216] AH01866: Optional hook test said: GET / HTTP/1.1
[Tue Oct 14 01:20:23.984535 2014] [optional_fn_export:error] [pid 10606:tid 140347682281216] AH01871: Optional function test said: GET / HTTP/1.1
[Tue Oct 14 01:20:24.026878 2014] [optional_hook_import:error] [pid 10611:tid 140347566892800] AH01866: Optional hook test said: GET / HTTP/1.1
[Tue Oct 14 01:20:24.026894 2014] [optional_fn_export:error] [pid 10611:tid 140347566892800] AH01871: Optional function test said: GET / HTTP/1.1
from filling up my error_log file located in /usr/local/apache/logs?

In my research I have found a site that shows the module responsible for creating all this junk. You can find it on this link (tigress.com/nobs/apache2-error-messages.html) but I will give you a snippet that looks like this:

Code:
Optional function test said: %s    +66 ./modules/test/mod_optional_fn_export.c    ap_log_error
Optional hook test said: %s    +62 ./modules/test/mod_optional_hook_import.c    ap_log_error
Basically from my understanding there is some type of test module that is compiled into Apache (even though I can't recall ever building apache with this module enabled, or if it even exits to be able to build) but none-the-less I would like to know how to remove it.

Thanks in advance!

Hello :)

The messages you provided are common when the system is out of memory. Do you notice any memory errors in /var/log/messages or low available memory overall when using the "free -m" command?

Thank you.
