Linux/RedHat/x86/RedHat56.zip is x64
Looks like the RH profile uploaded to Linux/RedHat/x86/RedHat56.zip is x64 instead of x86
I haven't looked at it yet, but why do you say that?
I was unsuccessful when attempting to use it with a memory dump for said config. During some troubleshooting, I noticed the following which made me believe it's for the wrong arch.:
