Could you send me your .map file? and what your database table looks 
like (its not a view is it?).  Also, how many rows are there in the 
table.  how are you calling the itemnquery.  is your machine (or the 
database) "busy" during the query.

I assume you're using a DATA/FILTER combination - lets see if thats the 
problem.  Use something like this;

DATA "the_geom FROM (SELECT oid,* FROM nodescomb_2003 WHERE nodeid in 
(...)  ) as foo USING UNIQUE oid USING SRID=..."

Fill in your appropriate SRID # and the list of values.
