Subject: [PATCH] rabbit: increase heartbeat rate to decrease poll interval
|
|
|
|
The poll_timeout is tied to the heartbeat_rate value when the
|
|
heartbeat_timeout_threshold is non-zero. It works out to be:
|
|
|
|
threshold / rate / 2
|
|
|
|
Therefore the default is 60 / 2 / 2 = 15. This causes the recv() to block for
|
|
up to 15 seconds unless there are incoming RPC messages. This is problematic
|
|
for graceful shutdown of services as the stop() request may block if the recv()
|
|
is blocked. To ensure that the recv() does not block for a long time we are
|
|
reducing the interval by controlling the rate.
