[UPDATE] [Solved]
Tried many things. Last one was with an Ubuntu 12.04 x64 LTS digital ocean droplet (instead of 14.04 x64).
Installed the same Couchbase 4.0.0 Community and Sync Gateway 1.2 Community on that server.
Setup the sync gateway same as in the original post but the error persisted.
As a last attempt, before falling back to “walrus” in memory server, I created a second bucket with a different name for use with the sync_gateway database.
Updated the config.json to use it. Restarted the sync gateways service… And guess what? It worked!!!
The interface services were started successfully on 4984 and 4985 as shown below.

Examining the buckets I noticed the bucked named “sync_gateway” was created with 4Mb and pre-filled with “[0]” where the new one had only around 400K.
Could it be there is some hardcoded handling for the bucket named as “sync_gateway”?
Or because the bucket originally named “sync_gateway” same as the database? Doesn’t make any sense to me. But anyway…
For now I’ll keep the Ubuntu 12.04 droplet as dev box… May upgrade it later…
Thanks!
