Thanks Fuad.
But why does just sorting provide an OOM. I executed the
query without adding the sort clause it executed perfectly. In fact I even
tried remove the maxrows=10 and executed. it came out fine. Queries with bigger
results seems to come out fine too. But why just sort of that too just 10 rows??
