<span style=" font-size:12pt;font-family:Arial">The short answer is there
is no easy way to determine what file/directory a waiter may be related.
 Generally, it is not necessary to know the file/directory since a
properly sized/configured cluster should not have long waiters occurring,
unless there is some type of failure in the cluster.  If you were
to capture sufficient information across the cluster you might be able
to work out the file/directory involved in a long waiter but it would take
either trace, or combing through lots of internal data structures.</span><br><br><span style=" font-size:12pt;font-family:Arial">It would be helpful
to know more details about your cluster to provide suggestions for what
may be causing the long waiters.  I presume you are seeing them on
a regular basis and would like to understand why they are occurring.</span><br><br><span style=" font-size:10pt;font-family:sans-serif">Regards, The Spectrum
