ConfigurationException and OperationTimeoutException with 1 machine down, or in Pend (warm-up) state

looks like this post is related Couchbase buckets shutting down and server going to pending state so if you’re from the same team maybe you can continue inquiry on pending state there?

otherwise I’d suggest to “reply as a new topic” in the Couchbase server category and I’ll try to ping a few folks and dig up the correct documentation.
