Aw, Snap! : Chrome showing error but FireFox showing correctly.

--- CI3 ---
when reducing records to 6900 then it is showing correctly in Chrome.
but in FireFox we tested same page for 15000 records (more than double) then again it is showing all the records.
it means DataTable is not limiting but Chrome.

is here anybody solved this problem before? if so, please help.
