Service Unavailable errors

    Hi Guys

    I have a windows 2003 standard edition with plesk 7.5 installed, I always had problems with the web sites at random (no particular web site) all of a sudden showing "Service Unavaliable" finally after lots of reading and research I found out that this is due to Application pool for that site being down

    This is the error I get in the error log:

    Event Type: Error
    Event Source: W3SVC
    Event Category: None
    Event ID: 1002
    Date: 7/18/2005
    Time: 12:37:54 AM
    User: N/A
    Computer: PLESK1
    Application pool 'lyroschen.com(pool)' is being automatically disabled due to a series of failures in the process(es) serving that application pool.

    For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

    So since I did not find any solution to this after months of research, I turned to EV1 support for help, they told me to turn off the Rapid-Fail protection in the application pool area, which I did. And indeed that fixed that problem, however, now I have a new issue, again at random time now the PHP pages stop responding and giving me and the clients this error:

    CGI Error
    The specified CGI application misbehaved by not returning a complete set of HTTP headers.

    Now the strange thing is that this error appears on all the sites on the server, so no one can run the PHP pages, as if the whole php engine was down, But Plesk control panel runs just fine, and it uses the same php parser but it uses a different webserver.

    This will keep going for about 15-20 minutes and then it clears up by itself, there are no error logs for this. I have applied all hot fixes from microsoft even one for the multiprocessor errors of getting "Service Unavailable"

    Did anyone else have this problem?

    Thanks in advance for any help you can give me on this issue.

    I have almost the same problem as jameszarr with 3 websites.

    we just installed php5 on our server and after a while when we typed the address into the browser the websites keept loading and loadin and never stoped (although nothing was shown other than a blank page).

    The solution we found for this was to create an application pool for each website and this worked except for 3 websites that always got the application pool stoped thus getting the Service Unavailable message.

    We are still trying to figure out what to do.

    why would these websites have problems? one of them is almost intirelly made in html, it only has 3 php forms to send an e-mail.
