msftefd.exe High CPU Usage on 2007 SP3 RRS feed

  • Question

  • OS: Microsoft Server 2008 x64 (with SP2)
    Exchange: 2007 SP3 Standard (with no update rollups)
    Databases: 4, totalling 100Gb altogether (all with IndexEnabled set to True)

    It seems that the 'Microsoft Exchange Search Indexer' constantly hammers my CPU, maxxing it out. There are no events of interest in the System or Application Log. By looking through all the Search-related performance counters, I see an ever-increasing rate of 'FB, ST terminated time out' and 'FB, ST unresponsive to shutdown'. From my Googling, here are the descriptions for those counters:

    FB, ST terminated time out: Number of terminated single-threaded filter daemons to date due to a time-out. A time out occurs when the FD takes too long to process a document. These timeouts are controlled by the FTE_FilterDaemonBatchAgingInterval and FTE_ChunkBufferTimeOutSeconds admin parameters.

    FB, ST unresponsive to shutdown: Number of times to date that the single-threaded filter daemons were given a directive to shutdown but didn't respond in time.

    Has anyone seen similar CPU activity for this search indexing service? What further steps can I do to troubleshoot the issue?
