SUSE Linux Enterprise Server 12 SP4
VMWare 6.7 or later
You run GroupWise in the clustered VMWare 6.7 or later environment and see GWIA becomes unavailable very often.
This is based on the customer feedback that run GroupWise 18 in VMWare 6.7 cluster environment. A virtual machine that hosted GWIA had a default EVC settings (Enhanced vMotion Compability) on the a CPU which is the "Skylake Generation". Changing this default CPU settings into "Westermere" solved the GWIA crash problems.
