[GitHub] [rocketmq] duhengforever commented on issue #475: After producer shutdown, can't callback checkLocalTransaction method.What should I do in production?

[GitHub]

@wangweifan In production, a cluster with same producerGroup is recommended, 
when a producer shutdown, broker will check for other surviving producers with 
the same producerGroup，and if there are no any surviving producers, broker will 
continue check after producer startup, so you need to be idempotent on both the 
producer side and the consumer side.
