Is the following statement still valid for VTune Amplifier XE 2018u2?
We are having this issue on VTune Amplifier XE 2016, and Intel support's suggestion was to try 2018u2.
We are seeing "SEP3_1" in the /var/log/messages log.

Some background questions:
- What version of Amplifier XE are you using?
- How many total cores (including HT if on)?
- Are there any error messages in the /var/log/messages log starting with 'SEP3_1' or 'amplxe-runsa'?
(An FYI for the likely cause of the problem: The hardware sampling driver allocates memory and the size of the allocation is determined by the number of cores. It is these memory allocations that can fail on machines with extremely large core counts and cause the OS to freeze.)
