Idle server got "confused", now won't respond/takes much CPU after start (3.0.1)

Update: found an older password maybe from a years-ago JIRA account, so that issue is halfway taken care of. I “filed” this forum post for the JIRA links: JIRA registration/reset links broken

(And looks like the collectinfo is done, so expect that soon! UPDATE: filed http://issues.couchbase.com/browse/MB-13403)
