# A client subscribing is sent every retained message under its filter at
# once, and mosquitto drops whatever does not fit its outgoing queue (1000
# messages by default) without telling it. Large sites retain far more than
# that, so a client subscribing widely (stagehand's hot list, source clearing
# or sweeping retained state) saw only part of it. A client that needs more
# can subscribe more narrowly, or refresh.
