High memory consumption

Hi there,

I have been seeing high memory consumption by similar SQLs from multiple processes which is eating up much resources in the server. SQL is shown below..

begin fndcp_tmsrv.read_message(:ec, :to, :typ, :enddt, :rid, :retid, :nl, :nc, :dl, :secgrp, :usr, :rspap, :rsp, :log, :app, :prg, :argc, :orgt, :orgid, :a1,  :a2,  :a3,  :a4,  :a5,  :a6,  :a7,  :a8,

 :a9,  :a10, :a11, :a12, :a13, :a14, :a15, :a16, :a17, :a18, :a19, :a20); end;

Any idea about this, and how can i eliminate this?

Thanks,

Saroj
