WES 7.2 Weekly Maint Index Fail

Any attempt to run the Index Maint returns the fail message below.  This is a new install of 7.2 with Rule Export from 5.5 and Import to 7.2.  Also STEMConfig backup from 5.5 and restored to new 7.2 server.

Windows 2008 Standard Server, Full SQL 2008.

All other aspects of the production environment seem to be running fine for the past three weeks.  It's just this Index job that is failing.

Any tips on Index cleanup or ideas.
