scheduling reboot / maintenance on dumps server

We've seen some kernel errors in the logs on the server that hosts the
dumps.  In order to upgrade and reboot, we need the currrently running
dumps to exit as soon as they complete the current phase of their runs.
I expect to complete this before the end of the week; if necessary I
will shoot existing processes to get it done.  In the meantime as dumps
complete, new ones will not be started; thanks for your patience.
