postwait/node-amqp library causes channel memory leak

[niho]

Problem

The RabbitMQ production server gets overloaded by new channels regularly and locks up because of the memory load. This seems to be caused by a bug in the postwait/node-amqp library that we are using. It seems to be creating a new AMQP channel each time a message is published, which obviously will cause serious problems.

Suggested solution

The node-amqp library has been marked as UNMAINTANED, so we need to look at moving to another library that is not buggy. There are multiple candidates:

• amqp-coffee from Dropbox
• rabbot which has a nice declarative API
• amqplib that claims almost 100% test coverage
• bramqp seems feature complete, but has complex API
