[rabbitmq-discuss] What is occuered when the master node output warning log of msg_store_persistent ?

[t.otoda]

Thank you for reply.

I made sure we shut down the server using 'rabbitmqctl stop'.
And our app disconnect the server when we shut down,
so any loads didn't depend on it.

Well, in case that message is output the server log,
does our app  have risks to be affected by using it ?
