 It is occasionally necessary to stop and restart the {{{pantasks_server}}} instances. For example, when it is necessary to [wiki:Processing#RebuildingtheIPPcode update and rebuild the code], or if pantasks itself becomes unresponsive or shows negative values in some columns of the status display (above).
 
-When stopping the pantasks, check with the others to find out if they have rogue pantasks running that should also be stopped (for example, heather with addstars, or chris/mark with rogue stack pantasks).

 The first command launches the {{{pantasks_servers}}} on the correct host, the second calls the three commands listed above ( {{{server input input; setup; run}}} ).

+== Stopping/Starting addstars ==

+There are a number of addstar pantasks currently in use for ippdvo  (note, not all may be active):
+
+ * ipp004: addstar
+ * ipp005: addstarlap
+ * ipp007: addstar007
+ * ipp008: addstar008
+ * ipp009: addstar009
+ * ipp010: addstar010
+
+=== to stop the addstars ===
+
+go into each directory and issue these commands:
+
+{{{
+cd ~ippdvo/addstar
+pantasks_client
+stop
+status
+
+}}}
+
+'''It is extremely important to wait until all the addstar tasks are done before shutting down addstar.  If you do not, you risk:
+   * causing an exposure to be addstarred twice
+   * destroying a minidvodb
+   * destroying the big mergedvodb 
+'''
+
+=== to start the addstars ===
+
+The best is to ask heather for advice on this, because different addstars will be in different states of activity based on the addstar needs.  In general it can be restarted as above (for a single addstar), and this will not hurt anything as by default when addstar is started it has nothing to do. This is to keep heather's sanity.
