Tableau Server Stopped Working after Attempting to Refresh a Workbook

Issue

Tableau Server stopped working after the refresh of a workbook (whether the refresh was scheduled or manual) and the logs might show that hyper stopped working. 

Environment

Tableau Server 2018.3.3

Cause

When executing queries, Hyper generates machine code which appears invalid to the CPU. CPUs affected are noted as Skylake X CPU (or the equivalent 2nd generation Xeon SP). This behavior was related to issue 935899, which has been corrected in a recent version of Tableau Server.
