    So, every couple of weeks or so (it varies), all of the sites I'm hosting go down. However, I can still ssh into the server, so that's fine. Anyone have any ideas what would be causing this, and how to stop it from happening?? Thanks!

    There's nothing showing up in the error log (the one in /root/ispconfig/httpd/logs/error_log, only one I know of). This is the last entry, from the last time I started it:

    Code:
    [Sat Jun 21 10:23:58 2008] [notice] Apache configured -- resuming normal operations
    [Sat Jun 21 10:23:58 2008] [notice] Accept mutex: sysvsem (Default: sysvsem)

    I found this line in my SYSLOG:

    Jul 7 06:25:06 web exiting on signal 15

    I did some research, and it appears to deal with chip temp or something?

    Are there any other errors in the logs in /var/log?

    I found this in my apache2/error.log:
    [Tue Jul 08 14:22:07 2008] [error] [client xx.xx.xx.xx] Invalid method in request \x80@\x01\x03

    Any other logs I should be looking into? Also, it's just the hosted sites that won't come up. I can still hit the ispconfig admin pages (which is a seperate apache instance, if I recall).

    What kind of set up do you have as for as an external IP address static or dynamic..If it is dynamic is that what is causing it every few weeks to go offline and your modifying tha in the ISPCONFIG Control Panel and then bringing it back up online? Also when it happens do you automatically reboot your router. Basically what I am saying have you ruled out all other components between the internet and your server.

    Nope, internet connection is fine. I can still ssh in and hit the ispconfig control panel from anywhere. And I never reboot the router, just the server.

    And even that's not working now (apparently the problem is getting worse). Usually, I can do a full reboot on the server, and everything comes back up. This time, I took it down, let it sit for a few hours, cleaned it out inside and all, and when I brought it back up, ssh and control panel, but no sites.

    Thanks for the help all!

    alright what showed up in your logs both the ones in ISPCONFIG and /var/log/

    also is there any errors if you just restart apache

    I don't see anything out of the ordinary showing up in those logs. Is there a particular log I should be looking at in /var/log or elsewhere? (I've been looking at /var/log/apache2/error.log)

    Also, not seeing anything showing up in the ISPConfig logs. And, when I check the ISPConfig control panel, it shows this under services:
    Web-Server: Online
    FTP-Server: Online
    SMTP-Server: Online
    POP3-Server: Online
    BIND-Server: Online
    mySQL-Server: Online

    So, according to it, everything is up and running, but I can't access any of my web sites.

    I'll be online pretty much all day tomorrow after about 11AM Central Time. Enter a chat session at http://www.maleshfske.com/hcl. If it shows offline send me a Private Message and I'll get online. And we'll see if we can get this figure out. Then will post the solution if we figure it out back to the forum.

    Well it is listening. When you try to go to the site that you are hosting what error message do you get in your browser? also I will be online after about 2 P.M. and I would be willing to give you a hand then.

    It just times out, and throws a "Connection has timed out. The server at www.mysite.net is taking too long to respond."

    Ok, after chatting with tmaleshafske and doing some more searching, it appears the problem did lie in my router. I found an old port forwarding/triggering entry in there, that when I disabled it, everything came up. Not sure why it was so intermittent, or why it took so long to show up (I've been running these sites for months, and haven't touched the router in as long), but, it's working, so all is good. Thanks for the help all!
