Couchbase Server Crashing - ubuntu 12.04

Question

I have just set up a Ubuntu 12.04 x64 droplet on digital ocean and I have freshly installed couchbase 2.5.0 x64.

I am in the admin panel, and everything looks fine until I click on "documents" in the databucket tab.

I get a connection lost message then end up at the login screen again.

This is what appears in my log after logging back in:

Port server moxi on node 'babysitter_of_ns_1@127.0.0.1' exited with status 0.      Restarting.

EOL on stdin. Exiting

If anyone could shine a light on this I would be most grateful. I have search and search on Google but feel like I'm hitting brick walls

UPDATE

My Droplet was 512mb ram and I resized it to 1GB and now it works. I also added a swap file to the server.

I will leave this here incase someone else comes across this problem.

Answer 1

As a reference Couchbase themselves recommend minimum spec machines to have the following characteristics:

Minimum Spec if using Key/Value only:

Processor: Dual-core CPU running at 2GHz RAM: 4GB

Minimum Spec if using Key/Value AND Views or XDCR:

Processor: Six cores running at 3GHz RAM: 16GB

Also bare in mind the following two things are very important:

For smaller systems, such as those with less than 16GB you should allocate at least 40% of RAM to your operating system.

and

At least twice the disk space to match your physical RAM for persistence of information

P.s. It is possible to run on much lower spec machines but I 100% wouldn't recommend it for production.
