Running requests will remain running and CM will actually stop only when
there are no running requests left. So, if you need to bounce CMs quickly,
make sure that there are no long-running requests running at the moment or
be prepared to terminate those.
Pending requests will remain pending and will be prevented from starting
while CMs are being shut down.

When you stop CMs there are no running requests (because CMs are stopped).
However, there are some occasions when statuses in the database show that
the request is running even if it's not (for example if you kill DB
processes for the requests after CMs are sent to shut down). cmclean script
fixes those wrong statuses.
Nothing happens to the pending requests, they remain pending end will run
after CMs start up and star date is met.

best regards,
Maris
