WFE Server CPU at 100% for W3WP3.exe

    คำถาม

  • Hi,

    One of my WFE server's CPU is constanly running at 100%.  It is the W3WP.exe process.  It is pointing to the main web aplication app pool.  It use IISPeek to see what's going on and here's the main cause it reported back:

    =========
    Collaboration AppPool
    pid (7108)
    REQUEST: 14771806791734011480     VERB: POST     URL: /rd/_vti_bin/sitedata.asmx
    ELAPSED: 1     PIPE-STATE: Processing     TIME-IN-STATE: 0
    CLIENT-IP: 10.12.30.250     PORT: 80
    ================

    Based on the above, it is point to the RD site collection that is causing the CPU spike.  The "_vti_bin/sitedata.asmx" is the Sharepoint Web Services.  I look at the site, it does not have anything other than the default Announcements, Links, etc.  There are, however, a bunch of subsite but this should not cause it as it is point to the RD (top level site) and each subsites would have its own "_vti_bin/sitedata.asmx".

    I can stop and restart the process... but it would spike up again after some time.  So, how can I figure out what in that site is causing this?

    Thanks in advance.
