Another CPU 100% w3wp.exe issue?

    Hi,

    We are running Windows 2003 SP2 and IIS v6.0. We have CMS 2002, and are
    running in mixed mode, with both asp, and asp.net pages.

    We have periods where the CPU is around 100%, and stays there. Sometimes
    this is for a couple of minutes, sometimes its for 15 minutes. If I leave
    it, no matter how long it stays around the 100% mark, it does seem to settle
    back down in the end. The trouble is that this could be quite some time, and
    meanwhile, some users will get timeouts, whilst some still get pages.

    I am a complete newbie when it comes to debugging processes. And I have
    read on here various threads related to iisstart, and windbg.

    Is there somewhere that explains the process of debugging, and exactly what
    to do?

    Thanks for any help.


    regards

    Steve G

    I should of also added, that if I kill the worker process thats at 100%,
    within seconds it starts up again under a new thread ID, and goes straight
    back to 100%.

    And although I expect it to restart, I was kind of hoping that by killing
    the process, it would stop anything that was interfering with it at that
    particular time.

    regards

    Alvin,

    The eventlog for the web/cms server has quite a few warnings, but they all
    seem to resemble the following :

    An unrecognized request was received by the CMS ISAPI Filter. The request
    was mapped to the CMS read-only resource cache virtual directory but the URL
    format did not correspond to a CMS Resource.

    I am also researching this error.
