If I remember correctly, a “map error” is telling you that you’ve run out of
memory.
You’re asking for 1GB for each, I assume you have that free? I also see you’re
not
using hugepages, so there “shouldn’t” be anything at /dev/hugepages/cache or
dev/hugepages/data,
but you have those as the path… /dev is protected, maybe you should try
starting as sudo or
move the path to somewhere open (like /tmp).
I think I saw that your cache size was set to 0, so that one won’t matter. I
run my containers as --privledged also.

David

I've now removed docker from the picture. I simply download the bin
distribution onto my 8GB VM and copy the templates in conf w/o changes.
