+<sect1>I updated my Linux distribution and now Spider cannot read the users
+file or the dupefile, what is the problem?
+
+<P>
+Almost certainly this is a change in the db format of perl. Follow these
+few steps to correct the problem.
+
+<itemize>
+<item>stop the cluster (disable any autostart in inittab)
+<item>cd /spider/data
+<item>issue the command perl user_asc
+<item>restart the cluster
+</itemize>
+
+That should solve the problem.
