Error Condition CSP application closed the connection before sending a complete response.

Hi Team,

I am getting this error while i entered one field and hit search button. The screen spinning for few minutes and prompt this error.Error Condition CSP application closed the connection before sending a complete response. The job is still running in the backend. Is there anything wrong with this SQLQuery, S Select="SELECT * FROM Sample.Class"
S:EntryDate'="" Where=Where_" EntryDate = '"_EntryDate_"' AND"
S:Location'="" Where=Where_" Location ='"_Location_"' AND"
S:Brand'="" Where=Where_" Brand ='"_Brand_"' AND"
S:Model'="" Where=Where_" Model Like '"_Model_"%' AND"
S:LineNo'="" Where=Where_" LineNo Like '"_LineNo_"%'"
S:SortBy'="" OrderBy=" ORDER BY "_SortBy
s:SortBy="" OrderBy=" ORDER BY EntryTime ASC"
S:$E(Where,$L(Where)-3,$L(Where))=" AND" Where=$E(Where,1,$L(Where)-4)
S Qry=Select_$S($L(Where):" WHERE"_Where,1:"")_$S($L(OrderBy):OrderBy,1:"").

Thanks in Advance.
