Why many OPTIONS requests in apache log and on status page?

If you are worried about numerous lines of the following kind: 

::1 - - [19/Feb/2014:22:37:51 +0100] "OPTIONS * HTTP/1.0" 200 105
::1 - - [19/Feb/2014:22:39:03 +0100] "OPTIONS * HTTP/1.0" 200 105
::1 - - [19/Feb/2014:22:47:17 +0100] "OPTIONS * HTTP/1.0" 200 105
::1 - - [19/Feb/2014:22:47:18 +0100] "OPTIONS * HTTP/1.0" 200 105
::1 - - [19/Feb/2014:22:47:19 +0100] "OPTIONS * HTTP/1.0" 200 105
::1 - - [19/Feb/2014:22:48:21 +0100] "OPTIONS * HTTP/1.0" 200 105

in your access_log or on apache status page, please stay calm, that does not denote anything wrong happening on your server. The answer is so simple, those are requests from the server to itself.

When the Apache HTTP Server manages its child processes, it needs a way to wake up processes that are listening for new connections. To do this, it sends a simple HTTP request back to itself. This request will appear in the access_log file with the remote address set to the loop-back interface (typically or ::1 if IPv6 is configured). If you log the User-Agent string (as in the combined log format), you will see the server signature followed by "(internal dummy connection)" on non-SSL servers. During certain periods you may see up to one such request for each httpd child process. 

These requests are perfectly normal and you do not, in general, need to worry about them. They can simply be ignored.
