Help: Sampling always fails when the run time is long

[shengmei_li]

Hello, I use vtune 9.0 for linux in Intel em64-bit machine. The application I launched is shell programmes.

When the sampling time is long, the error appears as:
Remote agent on psl-em64t-ibm1.bj.intel.com port33856
reports:
[ERROR] Attempt to perform sampling failed
[ERROR] unable to stop driver(error=60):There is no sampling session in progress

This error appears very often. Sometimes it can be avoided by modifying the iterations from 3 to 1.

For runs of 10 minutes or more, you probably want to raise the sample after values from the defaults so as to limit the sample data collection.
