   There where a few other procs, all small select statements and update 
statements, and all in a "locked" state.  I don't want to have to upgrade to 
Oracle for a problem that only happens every few weeks.  For the most part 
the system is very fast.   If there any way to isolate this query and remove 
the ability for rt to do perform it?
