Hard Out Of Memory Error

Couchbase Server

I’m getting for one of the buckets the following error:

Hard Out Of Memory Error. Bucket “*****” on node ****** is full. All memory allocated to this bucket is used for metadata.

We use Version 2.1.1 community edition (build-764)

I am too getting same error. Question is how to increase the RAM for the particular bucket via Command Prompt
