One way to address this would be to make sure that the upstream sink or
client can be routed to a different agent when necessary. That way when you
do want to restart the file channel, you would first route all the traffic
elsewhere, drain the channel and then do the shutdown as necessary. Once
the system is back up, you could route the traffic back to this agent.

I am sure that there are multiple other ways of doing this.
