So all of these > threads will queue flushes at about the same time. > This was supposed to be mitigated by Delayed. However that isn't nearly > enough. This results in the immediate filling up and then draining of the > flush queues every hour. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
