Everytime I try to get connect to couchbase in any way (via PHP, cli, etc). I have tried to use the command: service couchbase-server (start/stop/restart) and each has failed. I’m kind of at a standstill as to what the issue is and how to fix it. I’ve used the linux command ‘free’ to see I’ve ran out of RAM but plenty is available. Please help and let me know how to solve this issue and prevent it from happening as this has put a stand still on db requests and post. I’m using Couchbase 2.0 on a ubuntu 12.04 server.
