Whenever I think about Erlang's stability I recall the problems mentioned by CouchDB authors and RabbitMQ users. Apparently CouchDB hit some problems with low level disk access that they couldn't trace and that pushed them to migrate away from Erlang. RabbitMQ is allegedly dropping lots of messages for unknown reasons under heavy use. I do not have the links at hand for reference but such stories make me wonder how battle-tested Erlang really is when you need to persist your data (and not just transmit it over the network).
