    Exclamation Apache problem! Help needed quickly!

    The power went out in the room my server is in, and upon restarting it it won't serve any webpages. When I restart Apache I get this in Apache's error.log
    Code:
    [Sat Aug 02 20:37:48 2008] [notice] caught SIGWINCH, shutting down gracefully
    [Sat Aug 02 20:37:53 2008] [notice] Apache/2.2.8 (Ubuntu) PHP/5.2.4-2ubuntu5.3 with Suhosin-Patch configured -- resuming normal operations
    [Sat Aug 02 20:38:09 2008] [notice] caught SIGWINCH, shutting down gracefully
    I don't know what the problem is or how to fix it.

    Sounds like you may have SSL misconfigured. Try commenting out your SSL in your apache config.

    In apache2.conf, right?

    I'm not sure which part is SSL. Here's my apache2.conf:
    Code:
    #
    # Based upon the NCSA server configuration files originally by Rob McCool.
    #
    # This is the main Apache server configuration file.  It contains the
    # configuration directives that give the server its instructions.
    # See http://httpd.apache.org/docs/2.2/ for detailed information about
    # the directives.
    #
    # Do NOT simply read the instructions in here without understanding
    # what they do.  They're here only as hints or reminders.  If you are unsure
    # consult the online docs. You have been warned.  
    #
    # The configuration directives are grouped into three basic sections:
    #  1. Directives that control the operation of the Apache server process as a
    #     whole (the 'global environment').
    #  2. Directives that define the parameters of the 'main' or 'default' server,
    #     which responds to requests that aren't handled by a virtual host.
    #     These directives also provide default values for the settings
    #     of all virtual hosts.
    #  3. Settings for virtual hosts, which allow Web requests to be sent to
    #     different IP addresses or hostnames and have them handled by the
    #     same Apache server process.
    #
    # Configuration and logfile names: If the filenames you specify for many
    # of the server's control files begin with "/" (or "drive:/" for Win32), the
    # server will use that explicit path.  If the filenames do *not* begin
    # with "/", the value of ServerRoot is prepended -- so "/var/log/apache2/foo.log"
    # with ServerRoot set to "" will be interpreted by the
    # server as "//var/log/apache2/foo.log".
    #
    
    ### Section 1: Global Environment
    #
    # The directives in this section affect the overall operation of Apache,
    # such as the number of concurrent requests it can handle or where it
    # can find its configuration files.
    #
    
    #
    # ServerRoot: The top of the directory tree under which the server's
    # configuration, error, and log files are kept.
    #
    # NOTE!  If you intend to place this on an NFS (or otherwise network)
    # mounted filesystem then please read the LockFile documentation (available
    # at <URL:http://httpd.apache.org/docs-2.1/mod/mpm_common.html#lockfile>);
    # you will save yourself a lot of trouble.
    #
    # Do NOT add a slash at the end of the directory path.

    Re: Apache problem! Help needed quickly!

    Do you have virtual hosting set up on this box?

    Can you post the output of:

    Code:
    cat /var/log/apache2/error.log

    Re: Apache problem! Help needed quickly!

    As far as I know, I haven't set up virtual hosting.

    Attached is a copy of the error log I made right after the incident.

    Re: Apache problem! Help needed quickly!

    Can we take a look at your /etc/apache2/sites-avaialble/default?

    Also, check /var/run and see if there is an apache pid file and if there is delete it, and try the restart.

    Can you do an actual shut down and then do a restart instead of using the restart command?

    Re: Apache problem! Help needed quickly!

    I deleted the apache pid and when I tried to restart apache it didn't work. Doing the shutdown now.
    edit: after the shutdown I booted the server back up and did a restart on Apache, it restarted.

    Okay, here's the /etc/apache2/sites-available/default

    Code:
