vtune '-collect hotspots' does not work

Hi.I have strange profile results for my program:# amplxe-cl -duration=20 -collect hotspots ./nehtest 20000Warning: Failed to stop the sampling timer for the thread 7655.Warning: Failed to stop the sampling timer for the thread 7653.Using result path `./r002hs'Executing actions 16 % Loading data files Warning: Cannot load data file `./r002hs/data.0/7633-7637.0.log' ().Executing actions 75 % Generating a report Summary-------Elapsed Time: 3.315CPU Time: 3.247Executing actions 100 % doneamplxe-cl -duration=20 -collect hotspots ./nehtest 20000Warning: Failed to stop the sampling timer for the thread 7655.Warning: Failed to stop the sampling timer for the thread 7653.Using result path `./r002hs'Executing actions 16 % Loading data files Warning: Cannot load data file `./r002hs/data.0/7633-7637.0.log' ().Executing actions 75 % Generating a report Summary-------

For more complete information about compiler optimizations, see our Optimization Notice.

There have been several instances where similar
behavior was resolved by installing the latest version Update 7. Are you running Update 7? If not can you install the latest version?

Already have it:# amplxe-cl --versionIntel VTune Amplifier XE 2011 Update 7 (build 206420) Command Line ToolCopyright (C) 2009-2011 Intel Corporation.

For hotspots analysis, the -duration only specifies
the time limit in seconds for the analysis.
If your application runs for a shorter time than what duration is set
to, the analysis will stop. Can you let
me know how long your application runs outside of Intel VTune Amplifier XE? If it does run for only 3 or so seconds, can
you significantly increase the number of seconds your application runs to see if the behavior
changes? Can you let me know more about
the nature of your application ./nehtest? What libraries are being called? Are
you able to provide a sample application that reproduces the behavior?

Thanks
Rob
